13.1 Formatting a Research Paper

Learning objectives.

• Identify the major components of a research paper written using American Psychological Association (APA) style.
• Apply general APA style and formatting conventions in a research paper.

In this chapter, you will learn how to use APA style , the documentation and formatting style followed by the American Psychological Association, as well as MLA style , from the Modern Language Association. There are a few major formatting styles used in academic texts, including AMA, Chicago, and Turabian:

• AMA (American Medical Association) for medicine, health, and biological sciences
• APA (American Psychological Association) for education, psychology, and the social sciences
• Chicago—a common style used in everyday publications like magazines, newspapers, and books
• MLA (Modern Language Association) for English, literature, arts, and humanities
• Turabian—another common style designed for its universal application across all subjects and disciplines

While all the formatting and citation styles have their own use and applications, in this chapter we focus our attention on the two styles you are most likely to use in your academic studies: APA and MLA.

If you find that the rules of proper source documentation are difficult to keep straight, you are not alone. Writing a good research paper is, in and of itself, a major intellectual challenge. Having to follow detailed citation and formatting guidelines as well may seem like just one more task to add to an already-too-long list of requirements.

Following these guidelines, however, serves several important purposes. First, it signals to your readers that your paper should be taken seriously as a student’s contribution to a given academic or professional field; it is the literary equivalent of wearing a tailored suit to a job interview. Second, it shows that you respect other people’s work enough to give them proper credit for it. Finally, it helps your reader find additional materials if he or she wishes to learn more about your topic.

Furthermore, producing a letter-perfect APA-style paper need not be burdensome. Yes, it requires careful attention to detail. However, you can simplify the process if you keep these broad guidelines in mind:

• Work ahead whenever you can. Chapter 11 “Writing from Research: What Will I Learn?” includes tips for keeping track of your sources early in the research process, which will save time later on.
• Get it right the first time. Apply APA guidelines as you write, so you will not have much to correct during the editing stage. Again, putting in a little extra time early on can save time later.
• Use the resources available to you. In addition to the guidelines provided in this chapter, you may wish to consult the APA website at http://www.apa.org or the Purdue University Online Writing lab at http://owl.english.purdue.edu , which regularly updates its online style guidelines.

General Formatting Guidelines

This chapter provides detailed guidelines for using the citation and formatting conventions developed by the American Psychological Association, or APA. Writers in disciplines as diverse as astrophysics, biology, psychology, and education follow APA style. The major components of a paper written in APA style are listed in the following box.

These are the major components of an APA-style paper:

Body, which includes the following:

• Headings and, if necessary, subheadings to organize the content
• In-text citations of research sources
• References page

All these components must be saved in one document, not as separate documents.

The title page of your paper includes the following information:

• Title of the paper
• Author’s name
• Name of the institution with which the author is affiliated
• Header at the top of the page with the paper title (in capital letters) and the page number (If the title is lengthy, you may use a shortened form of it in the header.)

List the first three elements in the order given in the previous list, centered about one third of the way down from the top of the page. Use the headers and footers tool of your word-processing program to add the header, with the title text at the left and the page number in the upper-right corner. Your title page should look like the following example.

The next page of your paper provides an abstract , or brief summary of your findings. An abstract does not need to be provided in every paper, but an abstract should be used in papers that include a hypothesis. A good abstract is concise—about one hundred fifty to two hundred fifty words—and is written in an objective, impersonal style. Your writing voice will not be as apparent here as in the body of your paper. When writing the abstract, take a just-the-facts approach, and summarize your research question and your findings in a few sentences.

In Chapter 12 “Writing a Research Paper” , you read a paper written by a student named Jorge, who researched the effectiveness of low-carbohydrate diets. Read Jorge’s abstract. Note how it sums up the major ideas in his paper without going into excessive detail.

Write an abstract summarizing your paper. Briefly introduce the topic, state your findings, and sum up what conclusions you can draw from your research. Use the word count feature of your word-processing program to make sure your abstract does not exceed one hundred fifty words.

Depending on your field of study, you may sometimes write research papers that present extensive primary research, such as your own experiment or survey. In your abstract, summarize your research question and your findings, and briefly indicate how your study relates to prior research in the field.

Margins, Pagination, and Headings

APA style requirements also address specific formatting concerns, such as margins, pagination, and heading styles, within the body of the paper. Review the following APA guidelines.

Use these general guidelines to format the paper:

• Set the top, bottom, and side margins of your paper at 1 inch.
• Use double-spaced text throughout your paper.
• Use a standard font, such as Times New Roman or Arial, in a legible size (10- to 12-point).
• Use continuous pagination throughout the paper, including the title page and the references section. Page numbers appear flush right within your header.
• Section headings and subsection headings within the body of your paper use different types of formatting depending on the level of information you are presenting. Additional details from Jorge’s paper are provided.

Begin formatting the final draft of your paper according to APA guidelines. You may work with an existing document or set up a new document if you choose. Include the following:

• Your title page
• The abstract you created in Note 13.8 “Exercise 1”
• Correct headers and page numbers for your title page and abstract

APA style uses section headings to organize information, making it easy for the reader to follow the writer’s train of thought and to know immediately what major topics are covered. Depending on the length and complexity of the paper, its major sections may also be divided into subsections, sub-subsections, and so on. These smaller sections, in turn, use different heading styles to indicate different levels of information. In essence, you are using headings to create a hierarchy of information.

The following heading styles used in APA formatting are listed in order of greatest to least importance:

• Section headings use centered, boldface type. Headings use title case, with important words in the heading capitalized.
• Subsection headings use left-aligned, boldface type. Headings use title case.
• The third level uses left-aligned, indented, boldface type. Headings use a capital letter only for the first word, and they end in a period.
• The fourth level follows the same style used for the previous level, but the headings are boldfaced and italicized.
• The fifth level follows the same style used for the previous level, but the headings are italicized and not boldfaced.

Visually, the hierarchy of information is organized as indicated in Table 13.1 “Section Headings” .

Table 13.1 Section Headings

A college research paper may not use all the heading levels shown in Table 13.1 “Section Headings” , but you are likely to encounter them in academic journal articles that use APA style. For a brief paper, you may find that level 1 headings suffice. Longer or more complex papers may need level 2 headings or other lower-level headings to organize information clearly. Use your outline to craft your major section headings and determine whether any subtopics are substantial enough to require additional levels of headings.

Working with the document you developed in Note 13.11 “Exercise 2” , begin setting up the heading structure of the final draft of your research paper according to APA guidelines. Include your title and at least two to three major section headings, and follow the formatting guidelines provided above. If your major sections should be broken into subsections, add those headings as well. Use your outline to help you.

Because Jorge used only level 1 headings, his Exercise 3 would look like the following:

Citation Guidelines

In-text citations.

Throughout the body of your paper, include a citation whenever you quote or paraphrase material from your research sources. As you learned in Chapter 11 “Writing from Research: What Will I Learn?” , the purpose of citations is twofold: to give credit to others for their ideas and to allow your reader to follow up and learn more about the topic if desired. Your in-text citations provide basic information about your source; each source you cite will have a longer entry in the references section that provides more detailed information.

In-text citations must provide the name of the author or authors and the year the source was published. (When a given source does not list an individual author, you may provide the source title or the name of the organization that published the material instead.) When directly quoting a source, it is also required that you include the page number where the quote appears in your citation.

This information may be included within the sentence or in a parenthetical reference at the end of the sentence, as in these examples.

Epstein (2010) points out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).

Here, the writer names the source author when introducing the quote and provides the publication date in parentheses after the author’s name. The page number appears in parentheses after the closing quotation marks and before the period that ends the sentence.

Addiction researchers caution that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (Epstein, 2010, p. 137).

Here, the writer provides a parenthetical citation at the end of the sentence that includes the author’s name, the year of publication, and the page number separated by commas. Again, the parenthetical citation is placed after the closing quotation marks and before the period at the end of the sentence.

As noted in the book Junk Food, Junk Science (Epstein, 2010, p. 137), “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive.”

Here, the writer chose to mention the source title in the sentence (an optional piece of information to include) and followed the title with a parenthetical citation. Note that the parenthetical citation is placed before the comma that signals the end of the introductory phrase.

David Epstein’s book Junk Food, Junk Science (2010) pointed out that “junk food cannot be considered addictive in the same way that we think of psychoactive drugs as addictive” (p. 137).

Another variation is to introduce the author and the source title in your sentence and include the publication date and page number in parentheses within the sentence or at the end of the sentence. As long as you have included the essential information, you can choose the option that works best for that particular sentence and source.

Citing a book with a single author is usually a straightforward task. Of course, your research may require that you cite many other types of sources, such as books or articles with more than one author or sources with no individual author listed. You may also need to cite sources available in both print and online and nonprint sources, such as websites and personal interviews. Chapter 13 “APA and MLA Documentation and Formatting” , Section 13.2 “Citing and Referencing Techniques” and Section 13.3 “Creating a References Section” provide extensive guidelines for citing a variety of source types.

Writing at Work

APA is just one of several different styles with its own guidelines for documentation, formatting, and language usage. Depending on your field of interest, you may be exposed to additional styles, such as the following:

• MLA style. Determined by the Modern Languages Association and used for papers in literature, languages, and other disciplines in the humanities.
• Chicago style. Outlined in the Chicago Manual of Style and sometimes used for papers in the humanities and the sciences; many professional organizations use this style for publications as well.
• Associated Press (AP) style. Used by professional journalists.

References List

The brief citations included in the body of your paper correspond to the more detailed citations provided at the end of the paper in the references section. In-text citations provide basic information—the author’s name, the publication date, and the page number if necessary—while the references section provides more extensive bibliographical information. Again, this information allows your reader to follow up on the sources you cited and do additional reading about the topic if desired.

The specific format of entries in the list of references varies slightly for different source types, but the entries generally include the following information:

• The name(s) of the author(s) or institution that wrote the source
• The year of publication and, where applicable, the exact date of publication
• The full title of the source
• For books, the city of publication
• For articles or essays, the name of the periodical or book in which the article or essay appears
• For magazine and journal articles, the volume number, issue number, and pages where the article appears
• For sources on the web, the URL where the source is located

The references page is double spaced and lists entries in alphabetical order by the author’s last name. If an entry continues for more than one line, the second line and each subsequent line are indented five spaces. Review the following example. ( Chapter 13 “APA and MLA Documentation and Formatting” , Section 13.3 “Creating a References Section” provides extensive guidelines for formatting reference entries for different types of sources.)

In APA style, book and article titles are formatted in sentence case, not title case. Sentence case means that only the first word is capitalized, along with any proper nouns.

Key Takeaways

• Following proper citation and formatting guidelines helps writers ensure that their work will be taken seriously, give proper credit to other authors for their work, and provide valuable information to readers.
• Working ahead and taking care to cite sources correctly the first time are ways writers can save time during the editing stage of writing a research paper.
• APA papers usually include an abstract that concisely summarizes the paper.
• APA papers use a specific headings structure to provide a clear hierarchy of information.
• In APA papers, in-text citations usually include the name(s) of the author(s) and the year of publication.
• In-text citations correspond to entries in the references section, which provide detailed bibliographical information about a source.

How to Format a Scientific Paper

#scribendiinc

Written by  Joanna Kimmerly-Smith

You've done the research. You've carefully recorded your lab results and compiled a list of relevant sources. You've even written a draft of your scientific, technical, or medical paper, hoping to get published in a reputable journal. But how do you format your paper to ensure that every detail is correct? If you're a scientific researcher or co-author looking to get your research published, read on to find out how to format your paper.

While it's true that you'll eventually need to tailor your research for your target journal, which will provide specific author guidelines for formatting the paper (see, for example, author guidelines for publications by Elsevier , PLOS ONE , and  mBio ), there are some formatting rules that are useful to know for your initial draft. This article will explore some of the formatting rules that apply to all scientific writing, helping you to follow the correct order of sections ( IMRaD ), understand the requirements of each section, find resources for standard terminology and units of measurement, and prepare your scientific paper for publication.

Format Overview

The four main elements of a scientific paper can be represented by the acronym IMRaD: introduction, methods, results, and discussion. Other sections, along with a suggested length,* are listed in the table below.

* Length guidelines are taken from https://www.elsevier.com/connect/11-steps-to-structuring-a-science-paper-editors-will-take-seriously#step6 .

Now, let's go through the main sections you might have to prepare to format your paper.

On the first page of the paper, you must present the title of the paper along with the authors' names, institutional affiliations, and contact information. The corresponding author(s) (i.e., the one[s] who will be in contact with the reviewers) must be specified, usually with a footnote or an asterisk (*), and their full contact details (e.g., email address and phone number) must be provided. For example:

Dr. Clara A. Bell 1, * and Dr. Scott C. Smith 2

1 University of Areopagitica, Department of Biology, Sometown, Somecountry

2 Leviathan University, Department of Biochemistry and Biomedical Sciences, Sometown, Somecountry

*[email protected]

FORMATTING TIPS:

• If you are unsure of how to classify author roles (i.e., who did what), guidelines are available online. For example, American Geophysical Union (AGU) journals now recommend using Contributor Roles Taxonomy (CRediT), an online taxonomy for author contributions.

In this summary of your research, you must state your subject (i.e., what you did) and encapsulate the main findings and conclusions of your paper.

• Do not add citations in an abstract (the reader might not be able to access your reference list).
• Avoid using acronyms and abbreviations in the abstract, as the reader may not be familiar with them. Use full terms instead.

Below the abstract, include a list of key terms to help other researchers locate your study. Note that "keywords" is one word (with no space) and is followed by a colon:

Keywords : paper format, scientific writing.

• Check whether "Keywords" should be italicized and whether each term should be capitalized.
• Check the use of punctuation (e.g., commas versus semicolons, the use of the period at the end).
• Some journals (e.g., IEEE ) provide a taxonomy of keywords. This aids in the classification of your research.

Introduction

This is the reader's first impression of your paper, so it should be clear and concise. Include relevant background information on your topic, using in-text citations as necessary. Report new developments in the field, and state how your research fills gaps in the existing research. Focus on the specific problem you are addressing, along with its possible solutions, and outline the limitations of your study. You can also include a research question, hypothesis, and/or objectives at the end of this section.

• Organize your information from broad to narrow (general to particular). However, don't start too broad; keep the information relevant.
• You can use in-text citations in this section to situate your research within the body of literature.

This is the part of your paper that explains how the research was done. You should relate your research procedures in a clear, logical order (i.e., the order in which you conducted the research) so that other researchers can reproduce your results. Simply refer to the established methods you used, but describe any procedures that are original to your study in more detail.

• Identify the specific instruments you used in your research by including the manufacturer’s name and location in parentheses.
• Stay consistent with the order in which information is presented (e.g., quantity, temperature, stirring speed, refrigeration period).

Now that you've explained how you gathered your research, you've got to report what you actually found. In this section, outline the main findings of your research. You need not include too many details, particularly if you are using tables and figures. While writing this section, be consistent and use the smallest number of words necessary to convey your statistics.

• Use appendices or supplementary materials if you have too much data.
• Use headings to help the reader follow along, particularly if your data are repetitive (but check whether your style guide allows you to use them).

In this section, you interpret your findings for the reader in relation to previous research and the literature as a whole. Present your general conclusions, including an assessment of the strengths and weaknesses of the research and the implications of your findings. Resolve the hypothesis and/or research question you identified in the introduction.

• Use in-text citations to support your discussion.
• Do not repeat the information you presented in the results or the introduction unless it is necessary for a discussion of the overall implications of the research.

This section is sometimes included in the last paragraph of the discussion. Explain how your research fits within your field of study, and identify areas for future research.

• Keep this section short.

Acknowledgments

Write a brief paragraph giving credit to any institution responsible for funding the study (e.g., through a fellowship or grant) and any individual(s) who contributed to the manuscript (e.g., technical advisors or editors).

• Check whether your journal uses standard identifiers for funding agencies (e.g., Elsevier's Funder Registry ).

Conflicts of Interest/Originality Statement

Some journals require a statement attesting that your research is original and that you have no conflicts of interest (i.e., ulterior motives or ways in which you could benefit from the publication of your research). This section only needs to be a sentence or two long.

Here you list citation information for each source you used (i.e., author names, date of publication, title of paper/chapter, title of journal/book, and publisher name and location). The list of references can be in alphabetical order (author–date style of citation) or in the order in which the sources are presented in the paper (numbered citations). Follow your style guide; if no guidelines are provided, choose a citation format and be consistent .

• While doing your final proofread, ensure that the reference list entries are consistent with the in-text citations (i.e., no missing or conflicting information).
• Many citation styles use a hanging indent and may be alphabetized. Use the styles in Microsoft Word to aid you in citation format.
• Use EndNote , Mendeley , Zotero , RefWorks , or another similar reference manager to create, store, and utilize bibliographic information.

Appendix/Supplementary Information

In this optional section, you can present nonessential information that further clarifies a point without burdening the body of the paper. That is, if you have too much data to fit in a (relatively) short research paper, move anything that's not essential to this section.

• Note that this section is uncommon in published papers. Before submission, check whether your journal allows for supplementary data, and don't put any essential information in this section.

Beyond IMRaD: Formatting the Details

Aside from the overall format of your paper, there are still other details to watch out for. The sections below cover how to present your terminology, equations, tables and figures, measurements, and statistics consistently based on the conventions of scientific writing.

Terminology

Stay consistent with the terms you use. Generally, short forms can be used once the full term has been introduced:

• full terms versus acronyms (e.g., deoxyribonucleic acid versus DNA);
• English names versus Greek letters (e.g., alpha versus α); and
• species names versus short forms (e.g., Staphylococcus aureus versus S. aureus ).

One way to ensure consistency is to use standard scientific terminology. You can refer to the following resources, but if you're not sure which guidelines are preferred, check with your target journal.

• For gene classification, use GeneCards , The Mouse Genome Informatics Database , and/or genenames.org .
• For chemical nomenclature, refer to the International Union of Pure and Applied Chemistry (IUPAC) Compendium of Chemical Terminology (the Gold Book ) and the  IUPAC–IUB Combined Commission on Biochemical Nomenclature .
• For marine species names, use the World Register of Marine Species (WoRMS) or the European Register of Marine Species (ERMS) .

Italics must be used correctly for scientific terminology. Here are a couple of formatting tips:

• Species names, which are usually in Greek or Latin, are italicized (e.g., Staphylococcus aureus ).
• Genes are italicized, but proteins aren't.

Whether in mathematical, scientific, or technical papers, equations follow a conventional format. Here are some tips for formatting your calculations:

• Number each equation you present in the text, inserting the number in parentheses.

X + Y = 1                                                                                                                                               (1)

• Check whether your target journal requires you to capitalize the word "Equation" or use parentheses for the equation number when you refer to equations within the text.

In Equation 1, X represents . . .

In equation (1), X represents . . .

(Note also that you should use italics for variables.)

• Try using MathType or Equation Editor in Microsoft Word to type your equations, but use Unicode characters when typing single variables or mathematical operators (e.g., x, ≥, or ±) in running text. This makes it easier to edit your text and format your equations before publication.
• In line with the above tip, remember to save your math equations as editable text and not as images in case changes need to be made before publication.

Tables and Figures

Do you have any tables, graphs, or images in your research? If so, you should become familiar with the rules for referring to tables and figures in your scientific paper. Some examples are presented below.

• Capitalize the titles of specific tables and figures when you refer to them in the text (e.g., "see Table 3"; "in Figure 4").
• In tables, stay consistent with the use of title case (i.e., Capitalizing Each Word) and sentence case (i.e., Capitalizing the first word).
• In figure captions, stay consistent with the use of punctuation, italics, and capitalization. For example:

Figure 1. Classification of author roles.

Figure 2: taxonomy of paper keywords

Measurements

Although every journal has slightly different formatting guidelines, most agree that the gold standard for units of measurement is the International System of Units (SI) . Wherever possible, use the SI. Here are some other tips for formatting units of measurement:

• Add spaces before units of measurement. For example, 2.5 mL not 2.5mL.
• Be consistent with your units of measure (especially date and time). For example, 3 hours or 3 h.

When presenting statistical information, you must provide enough specific information to accurately describe the relationships among your data. Nothing is more frustrating to a reviewer than vague sentences about a variable being significant without any supporting details. The author guidelines for the journal Nature recommend that the following be included for statistical testing: the name of each statistical analysis, along with its n value; an explanation of why the test was used and what is being compared; and the specific alpha levels and P values for each test.

Angel Borja, writing for Elsevier publications, described the statistical rules for article formatting as follows:

• Indicate the statistical tests used with all relevant parameters.
• Use mean and standard deviation to report normally distributed data.
• Use median and interpercentile range to report skewed data.
• For numbers, use two significant digits unless more precision is necessary.
• Never use percentages for very small samples.

Remember, you must be prepared to justify your findings and conclusions, and one of the best ways to do this is through factual accuracy and the acknowledgment of opposing interpretations, data, and/or points of view.

Even though you may not look forward to the process of formatting your research paper, it's important to present your findings clearly, consistently, and professionally. With the right paper format, your chances of publication increase, and your research will be more likely to make an impact in your field. Don't underestimate the details. They are the backbone of scientific writing and research.

Formatting guide

This guide describes how to prepare contributions for submission. We recommend you read this in full if you have not previously submitted a contribution to Nature . We also recommend that, before submission, you familiarize yourself with Nature ’s style and content by reading the journal, either in print or online, particularly if you have not submitted to the journal recently.

Formats for Nature contributions

Articles are the main format for original research contributions to Nature . In addition, Nature publishes other submitted material as detailed below.

Articles are original reports whose conclusions represent a substantial advance in understanding of an important problem and have immediate, far-reaching implications. In print, physical sciences papers do not normally exceed 6 pages on average, and biological, clinical and social-sciences papers do not normally exceed 8 pages on average. However, the final print length is at the editor’s discretion.

Articles start with a fully referenced summary paragraph, ideally of no more than 200 words, which is separate from the main text and avoids numbers, abbreviations, acronyms or measurements unless essential. It is aimed at readers outside the discipline. This summary paragraph should be structured as follows: 2-3 sentences of basic-level introduction to the field; a brief account of the background and rationale of the work; a statement of the main conclusions (introduced by the phrase 'Here we show' or its equivalent); and finally, 2-3 sentences putting the main findings into general context so it is clear how the results described in the paper have moved the field forwards. Please refer to our annotated example   to see how the summary paragraph should be constructed.

The typical length of a 6-page article with 4 modest display items (figures and tables) is 2500 words (summary paragraph plus body text). The typical length of an 8-page article with 5-6 modest display items is 4300 words. A ‘modest’ display item is one that, with its legend, occupies about a quarter of a page (equivalent to ~270 words). If a composite figure (with several panels) needs to occupy at least half a page in order for all the elements to be visible, the text length may need to be reduced accordingly to accommodate such figures. Keep in mind that essential but technical details can be moved into the Methods or Supplementary Information.

As a guideline, articles typically have no more than 50 references. (There is no such constraint on any additional references associated with Methods or Supplementary Information.)

Sections are separated with subheadings to aid navigation. Subheadings may be up to 40 characters (including spaces).

Word counts refer to the text of the paper. Title, author list, acknowledgements and references are not included in total word counts.

Matters Arising and Corrections

Matters Arising are exceptionally interesting or important comments and clarifications on original research papers or other peer-reviewed material published within the past 18 months in Nature . They are published online but not in print.

For further details of and instructions for how to submit such comments on peer-reviewed material published in Nature — or to notify editors of the potential need for a correction — please consult our Matters Arising page.

The editorial process

See this section for an explanation of Nature 's editorial criteria for publication, refereeing policy and how editors handle papers after submission. Submission to a Nature journal is taken by the journal to mean that all the listed authors have agreed to all of the contents. See authorship policy for more details.

Presubmission enquiries

If you wish to enquire whether your Article might be suitable for consideration by Nature , please use our online presubmission enquiry service . All presubmission enquiries must include a cover paragraph to the editor stating the interest to a broad scientific readership, a fully referenced summary paragraph, and a reference list.

Readability

Nature is an international journal covering all the sciences. Contributions should therefore be written clearly and simply so that they are accessible to readers in other disciplines and to readers for whom English is not their first language. Thus, technical jargon should be avoided as far as possible and clearly explained where its use is unavoidable. Abbreviations, particularly those that are not standard, should also be kept to a minimum. The background, rationale and main conclusions of the study should be clearly explained. Titles and abstracts in particular should be written in language that will be readily intelligible to any scientist. Essential but specialized terms should be explained concisely but not didactically.

For gene, protein and other specialized names authors can use their preferred terminology so long as it is in current use by the community, but they must give all known names for the entity at first use in the paper. Nature prefers authors to use internationally agreed nomenclature. Papers containing new or revised formal taxonomic nomenclature for animals, whether living or extinct, are accepted conditional on the provision of LSIDs (Life Science Identifiers) by means of registration of such nomenclature with ZooBank, the proposed online registration system for the International Code of Zoological Nomenclature (ICZN).

Even though no paper will be rejected because of poor language, non–native English speakers occasionally receive feedback from editors and reviewers regarding language and grammar usage in their manuscripts. You may wish to consider asking colleagues to read your manuscript and/or to use a professional editing service such as those provided by our affiliates Nature Research Editing Service or American Journal Experts . You can also get a fast, free grammar check of your manuscript that takes into account all aspects of readability in English. Please note that the use of a language editing service is not a requirement for publication in Nature .

Nature 's editors provide detailed advice about the expected print length when asking for the final version of the manuscript. Nature 's editors often suggest revised titles and rewrite the summary paragraphs of Articles so the conclusions are clear to a broad readership.

After acceptance, Nature 's subeditors (copyeditors) ensure that the text and figures are readable and clear to those outside the field, and edit papers into Nature 's house style. They pay particular attention to summary paragraphs, overall clarity, figures, figure legends and titles.

Proofs are sent before publication; authors are welcome to discuss proposed changes with Nature 's subeditors, but Nature reserves the right to make the final decision about matters of style and the size of figures.

A useful set of articles providing general advice about writing and submitting scientific papers can be found on the SciDev.Net website.

Format of Articles

Contributions should be double-spaced and written in English (spellings as in the Oxford English Dictionary ).

Contributions should be organized in the sequence: title, authors, affiliations (plus present addresses), bold first paragraph, main text, main references, tables, figure legends, methods (including separate data and code availability statements), methods references, acknowledgements, author contributions, competing interest declaration, additional information (containing supplementary information line (if any) and corresponding author line), extended data figure/table legends. In order to facilitate the review process, for initial submissions we encourage authors to present the manuscript text and figures together in a single file (Microsoft Word or PDF, up to 30 MB in size). The figures may be inserted within the text at the appropriate positions or grouped at the end, and each figure legend should be presented together with its figure. Also, please include line numbers within the text.

Titles do not exceed two lines in print. This equates to 75 characters (including spaces). Titles do not normally include numbers, acronyms, abbreviations or punctuation. They should include sufficient detail for indexing purposes but be general enough for readers outside the field to appreciate what the paper is about.

An uninterrupted page of text contains about 1250 words.

A typical 6-page Article contains about 2,500 words of text and, additionally, 4 modest display items (figures and/or tables) with brief legends, reference list and online-only methods section if applicable. A composite figure (with several panels) usually needs to take about half a page, equivalent to about 600 words, in order for all the elements to be visible (see section 5.9 for instructions on sizing figures).

A typical 8-page Article contains about 4300 words of text and, additionally, 5-6 modest display items (figures and/or tables) with brief legends, reference list and online-only methods section if applicable. A composite figure (with several panels) usually needs to take about half a page, equivalent to about 600 words, in order for all the elements to be visible (see section 5.9 for instructions on sizing figures).

Authors of contributions that significantly exceed the limits stated here (or as specified by the editor) will have to shorten their papers before acceptance, inevitably delaying publication.

Nature requires authors to specify the contribution made by their co-authors in the end notes of the paper (see section 5.5). If authors regard it as essential to indicate that two or more co-authors are equal in status, they may be identified by an asterisk symbol with the caption ‘These authors contributed equally to this work’ immediately under the address list. If more than three co-authors are equal in status, this should be indicated in the author contributions statement. Present addresses appear immediately below the author list (below the footnote rule at the bottom of the first page) and may be identified by a dagger symbol; all other essential author-related explanation is placed in the acknowledgements.

Our preferred format for text is Microsoft Word, with the style tags removed.

TeX/LaTeX: If you have prepared your paper using TeX/LaTeX, we will need to convert this to Word after acceptance, before your paper can be typeset. All textual material of the paper (including references, tables, figure captions, online methods, etc.) should be included as a single .tex file.

We prefer the use of a ‘standard’ font, preferably 12-point Times New Roman. For mathematical symbols, Greek letters and other special characters, use normal text or Symbol font. Word Equation Editor/MathType should be used only for formulae that cannot be produced using normal text or Symbol font.

The ‘Methods’ section is in the main text file, following the figure legends. This Methods section will appear in the PDF and in the full-text (HTML) version of the paper online, but will not appear in the printed issue. The Methods section should be written as concisely as possible but should contain all elements necessary to allow interpretation and replication of the results. As a guideline, the Methods section does not typically exceed 3,000 words. To increase reproducibility, authors are encouraged to deposit a detailed description of protocols used in their study in a protocol sharing platform of their choice. Springer Nature’s protocols.io is a free and open service designed to help researchers share experimental know-how. Protocols deposited by the authors in www.protocols.io will be linked to the online Methods section upon publication

Detailed descriptions of methods already published should be avoided; a reference number can be provided to save space, with any new addition or variation stated.

The Methods section should be subdivided by short bold headings referring to methods used and we encourage the inclusion of specific subsections for statistics, reagents and animal models. If further references are included in this section their numbering should continue from the end of the last reference number in the rest of the paper and they are listed after the Methods section.

Please provide separate Data Availability and Code Availability statements after the main text statements and before the Extended Data legends; detailed guidance can be found in our data availability and data citations policy . Certain data types must be deposited in an appropriate public structured data depository (details are available here ), and the accession number(s) provided in the manuscript. Full access is required at the time of publication. Should full access to data be required for peer review, authors must provide it.

The Methods section cannot contain figures or tables (essential display items should be included in the Extended Data or exceptionally in the Supplementary Information).

References are each numbered, ordered sequentially as they appear in the text, tables, boxes, figure legends, Methods, Extended Data tables and Extended Data figure legends.

When cited in the text, reference numbers are superscript, not in brackets unless they are likely to be confused with a superscript number.

Do not use linked fields (produced by EndNote and similar programs). Please use the one-click button provided by EndNote to remove EndNote codes before saving your file.

As a guideline, Articles allow up to 50 references in the main text if needed and within the average page budget. Only one publication can be listed for each number. Additional references for Methods or Supplementary Information are not included in this count.

Only articles that have been published or accepted by a named publication, or that have been uploaded to a recognized preprint server (for example, arXiv, bioRxiv), should be in the reference list; papers in preparation should be mentioned in the text with a list of authors (or initials if any of the authors are co-authors of the present contribution).

Published conference abstracts, numbered patents, preprints on recognized servers, papers in press, and research datasets that have been assigned a digital object identifier may be included in reference lists, but text, grant details and acknowledgements may not. (An exception is the highlighted references which we ask authors of Reviews, Perspectives and Insights articles to provide.)

All authors should be included in reference lists unless there are more than five, in which case only the first author should be given, followed by ‘et al.’.

Please follow the style below in the published edition of Nature in preparing reference lists.

Authors should be listed surname first, followed by a comma and initials of given names.

Titles of all cited articles are required. Titles of articles cited in reference lists should be in upright, not italic text; the first word of the title is capitalized, the title written exactly as it appears in the work cited, ending with a full stop. Book titles are italic with all main words capitalized. Journal titles are italic and abbreviated according to common usage. Volume numbers are bold. The publisher and city of publication are required for books cited. (Refer to published papers in Nature for details.)

Research datasets may be cited in the reference list if they have been assigned digital object identifiers (DOIs) and include authors, title, publisher (repository name), identifier (DOI expressed as a URL). Example: Hao, Z., AghaKouchak, A., Nakhjiri, N. & Farahmand, A. Global Integrated Drought Monitoring and Prediction System (GIDMaPS) data sets. figshare http://dx.doi.org/10.6084/m9.figshare.853801 (2014).

Recognized preprints may be cited in the reference list. Example: Babichev, S. A., Ries, J. & Lvovsky, A. I. Quantum scissors: teleportation of single-mode optical states by means of a nonlocal single photon. Preprint at http://arXiv.org/quant-ph/0208066 (2002).

References to web-only journals should give authors, article title and journal name as above, followed by URL in full - or DOI if known - and the year of publication in parentheses.

References to websites should give authors if known, title of cited page, URL in full, and year of posting in parentheses.

End notes are brief and follow the Methods (or Methods References, if any).

Acknowledgements should be brief, and should not include thanks to anonymous referees and editors, inessential words, or effusive comments. A person can be thanked for assistance, not “excellent” assistance, or for comments, not “insightful” comments, for example. Acknowledgements can contain grant and contribution numbers.

Author Contributions: Authors are required to include a statement to specify the contributions of each co-author. The statement can be up to several sentences long, describing the tasks of individual authors referred to by their initials. See the authorship policy page for further explanation and examples.

Competing interests  statement.

Additional Information: Authors should include a set of statements at the end of the paper, in the following order:

Papers containing Supplementary Information contain the statement: “Supplementary Information is available for this paper.”

A sentence reading "Correspondence and requests for materials should be addressed to XX.” Nature expects this identified author to respond to readers’ enquiries and requests for materials, and to coordinate the handling of any other matters arising from the published contribution, including corrections complaints. The author named as corresponding author is not necessarily the senior author, and publication of this author’s name does not imply seniority. Authors may include more than one e-mail address if essential, in which event Nature will communicate with the first-listed address for any post-publication matters, and expect that author to coordinate with the other co-authors.

Peer review information includes the names of reviewers who agree to be cited and is completed by Nature staff during proofing.

A sentence reading “Reprints and permissions information is available at www.nature.com/reprints.”

Life sciences and behavioural & social sciences reporting guidelines

To improve the transparency of reporting and the reproducibility of published results, authors of life sciences and behavioural & social sciences Articles must provide a completed Reporting Summary that will be made available to editors and reviewers during manuscript assessment. The Reporting Summary will be published with all accepted manuscripts.

Please note: because of the advanced features used in these forms, you must use Adobe Reader to open the documents and fill them out.

Guidance and resources related to the use and reporting of statistics are available here .

Tables should each be presented on a separate page, portrait (not landscape) orientation, and upright on the page, not sideways.

Tables have a short, one-line title in bold text. Tables should be as small as possible. Bear in mind the size of a Nature page as a limiting factor when compiling a table.

Symbols and abbreviations are defined immediately below the table, followed by essential descriptive material as briefly as possible, all in double-spaced text.

Standard table formats are available for submissions of cryo-EM , NMR and X-ray crystallography data . Authors providing these data must use these standard tables and include them as Extended Data.

Figure legends

For initial submissions, we encourage authors to present the manuscript text and figures together in a single Word doc or PDF file, and for each figure legend to be presented together with its figure. However, when preparing the final paper to be accepted, we require figure legends to be listed one after the other, as part of the text document, separate from the figure files, and after the main reference list.

Each figure legend should begin with a brief title for the whole figure and continue with a short description of each panel and the symbols used. If the paper contains a Methods section, legends should not contain any details of methods. Legends should be fewer than 300 words each.

All error bars and statistics must be defined in the figure legend, as discussed above.

Nature requires figures in electronic format. Please ensure that all digital images comply with the Nature journals’ policy on image integrity .

Figures should be as small and simple as is compatible with clarity. The goal is for figures to be comprehensible to readers in other or related disciplines, and to assist their understanding of the paper. Unnecessary figures and parts (panels) of figures should be avoided: data presented in small tables or histograms, for instance, can generally be stated briefly in the text instead. Avoid unnecessary complexity, colouring and excessive detail.

Figures should not contain more than one panel unless the parts are logically connected; each panel of a multipart figure should be sized so that the whole figure can be reduced by the same amount and reproduced on the printed page at the smallest size at which essential details are visible. For guidance, Nature ’s standard figure sizes are 90 mm (single column) and 180 mm (double column) and the full depth of the page is 170 mm.

Amino-acid sequences should be printed in Courier (or other monospaced) font using the one-letter code in lines of 50 or 100 characters.

Authors describing chemical structures should use the Nature Research Chemical Structures style guide .

Some brief guidance for figure preparation:

Lettering in figures (labelling of axes and so on) should be in lower-case type, with the first letter capitalized and no full stop.

Units should have a single space between the number and the unit, and follow SI nomenclature or the nomenclature common to a particular field. Thousands should be separated by commas (1,000). Unusual units or abbreviations are defined in the legend.

Scale bars should be used rather than magnification factors.

Layering type directly over shaded or textured areas and using reversed type (white lettering on a coloured background) should be avoided where possible.

Where possible, text, including keys to symbols, should be provided in the legend rather than on the figure itself.

Figure quality

At initial submission, figures should be at good enough quality to be assessed by referees, preferably incorporated into the manuscript text in a single Word doc or PDF, although figures can be supplied separately as JPEGs if authors are unable to include them with the text. Authors are advised to follow the initial and revised submissions guidelines with respect to sizing, resolution and labelling.

Please note that print-publication quality figures are large and it is not helpful to upload them at the submission stage. Authors will be asked for high-quality figures when they are asked to submit the final version of their article for publication.At that stage, please prepare figures according to these guidelines .

Third party rights

Nature discourages the use or adaptation of previously published display items (for example, figures, tables, images, videos or text boxes). However, we recognize that to illustrate some concepts the use of published data is required and the reuse of previously published display items may be necessary. Please note that in these instances we might not be able to obtain the necessary rights for some images to be reused (as is, or adapted versions) in our articles. In such cases, we will contact you to discuss the sourcing of alternative material.

Figure costs

In order to help cover some of the additional cost of four-colour reproduction, Nature Portfolio charges our authors a fee for the printing of their colour figures. Please contact our offices for exact pricing and details. Inability to pay this charge will not prevent publication of colour figures judged essential by the editors, but this must be agreed with the editor prior to acceptance.

Production-quality figures

When a manuscript is accepted in principle for publication, the editor will ask for high-resolution figures. Do not submit publication-quality figures until asked to do so by an editor. At that stage, please prepare figures according to these guidelines .

Extended Data

Extended Data figures and tables are online-only (appearing in the online PDF and full-text HTML version of the paper), peer-reviewed display items that provide essential background to the Article but are not included in the printed version of the paper due to space constraints or being of interest only to a few specialists. A maximum of ten Extended Data display items (figures and tables) is typically permitted. See Composition of a Nature research paper .

Extended Data tables should be formatted along similar lines to tables appearing in print (see section 5.7) but the main body (excluding title and legend, which should be included at the end of the Word file) should be submitted separately as an image rather than as an editable format in Word, as Extended Data tables are not edited by Nature’s subediting department. Small tables may also be included as sub-panels within Extended Data figures. See Extended Data Formatting Guide .

Extended Data figures should be prepared along slightly different guidelines compared to figures appearing in print, and may be multi-panelled as long as they fit to size rules (see Extended Data Formatting Guide ). Extended Data figures are not edited or styled by Nature’s art department; for this reason, authors are requested to follow Nature style as closely as possible when preparing these figures. The legends for Extended Data figures should be prepared as for print figures and should be listed one after the other at the end of the Word file.

If space allows, Nature encourages authors to include a simple schematic, as a panel in an Extended Data figure, that summarizes the main finding of the paper, where appropriate (for example, to assist understanding of complex detail in cell, structural and molecular biology disciplines).

If a manuscript has Extended Data figures or tables, authors are asked to refer to discrete items at an appropriate place in the main text (for example, Extended Data Fig. 1 and Extended Data Table 1).

If further references are included in the Extended Data tables and Extended Data figure legends, the numbering should continue from the end of the last reference number in the main paper (or from the last reference number in the additional Methods section if present) and the list should be added to the end of the list accompanying the additional Methods section, if present, or added below the Extended Data legends if no additional Methods section is present.

Supplementary Information

Supplementary Information (SI) is online-only, peer-reviewed material that is essential background to the Article (for example, large data sets, methods, calculations), but which is too large or impractical, or of interest only to a few specialists, to justify inclusion in the printed version of the paper. See the Supplementary Information page for further details.

Supplementary Information should not contain figures (any figures additional to those appearing in print should be formatted as Extended Data figures). Tables may be included in Supplementary Information, but only if they are unsuitable for formatting as Extended Data tables (for example, tables containing large data sets or raw data that are best suited to Excel files).

If a manuscript has accompanying SI, either at submission or in response to an editor’s letter that requests it, authors are asked to refer to discrete items of the SI (for example, videos, tables) at an appropriate point in the main manuscript.

Chemical structures and characterization of chemical materials

For guidelines describing Nature ’s standards for experimental methods and the characterization of new compounds, please see the information sheet on the characterization of chemical materials .

We aim to produce chemical structures in a consistent format throughout our articles. Please use the Nature Portfolio Chemical Structures Guide and ChemDraw template to ensure that you prepare your figures in a format that will require minimal changes by our art and production teams. Submit final files at 100% as .cdx files.

Registered Reports

Registered Reports are empirical articles testing confirmatory hypotheses in which the methods and proposed analyses are pre-registered and peer reviewed prior to research being conducted. For further details about Registered Reports and instructions for how to submit such articles to Nature please consult our Registered Reports page.

All contributions should be submitted online , unless otherwise instructed by the editors. Please be sure to read the information on what to include in your cover letter as well as several important content-related issues when putting a submission together.

Before submitting, all contributors must agree to all of Nature's publication policies .

Nature authors must make data and materials publicly available upon publication. This includes deposition of data into the relevant databases and arranging for them to be publicly released by the online publication date (not after). A description of our initiative to improve the transparency and the reproducibility of published results is available here . A full description of Nature’s publication policies is at the Nature Portfolio Authors and Referees website .
