Note: If you are submitting a revised paper to the same journal, the response letter to the reviewers is different
from the cover letter used at initial submission. You can find tips and a template on writing effective response
letters to the reviewers in our previous article.

Many journals require a cover letter and state this in their guidelines for authors (alternatively known as authorguidelines, information for authors, guide for authors, guidelines for papers, submission guide, etc.). For some journals,
a cover letter is optional or may not be not required, but it’s probably a good idea to include one.

Why do some journals ask for cover letters?
Cover letters that include standard statements required by the journal allow the journal staff to quickly confirm thatthe authors have (or say they have) followed certain ethical research and publishing practices.
These statements assert that the authors followed standard practices, which may include (i) adhering to ethicalguidelines for research involving humans (Declaration of Helsinki), involving animals (ARRIVE guidelines), or fallingunder institutional guidelines; (ii) obtaining ethics approval from institutional review boards or ethics committees; (iii)
obtaining informed consent or assent from participants; (iv) complying with authorship criteria (e.g., ICMJE criteria); (v)confirming no duplicate submissions have been made; and (vi) recommending reviewers for your paper, which may
include specifying peers that you prefer not be contacted.

2 Cover letters can summarize your manuscript quickly for the journal editor, highlighting your most important

findings and their implications to show why your manuscript would be of interest.
Some journals, such as Nature, state that while a cover letter is optional, it provides “an excellent opportunity to briefly
discuss the importance of the submitted work and why it is appropriate for the journal.” Some publishers, such asSpringer, recommend that you write a cover letter to help “sell” your manuscript to the journal editor.
Cover letters that contain all of the information required by the journal (as stated in the guideline for authors) canindicate that you have spent time carefully formatting the manuscript to fit the journal’s style. This can create agood first impression. Addressing the letter to a named editor at the journal also shows that you took the time to write
your letter (and by extension, your manuscript) with care and considered the fit with the journal beyond just impact
factor.

3What makes an effective cover letter?
Cover letters should be short—preferably no more than 1 page—and they often use single line spacing. The content canbe broadly divided into six sections:

1.
2.
3.
4.
5.
6.

Addressee’s information and date of submission
Opening salutation
Purpose statement and administrative information
Summary of main research findings and implications
Statements or information required by the journal
Closing salutation and your contact information

Cover letters can be submitted
as normal text files, such as
Word, or input directly in afield in the journal’s online
submission system.

Let’s look at some tips for each section. And don’t forget to download the template, which shows these tips already inplace.

1. Addressee’s information and date of submission• Check the journal’s website for the name of the editor who handles submissions; this could be the Managing Editor
or an editor assigned to your geographical region. If no handling editor is named, address your cover letter to theEditor-in-Chief. Some journals ask that you identify a specific editor for your specialty.

••

Write the name of the addressee in the top left corner of the page.

•Note that dates written as numerals only can be confusing: 02/03/2017 can be read “2 March 2017” in British and “3February 2017” in American English. Using the format “3 February 2017” or “February 3, 2017” is clear.

Write the date beneath. To minimize the number of line breaks used in your cover letter (and help keep it to one
page of text), you can put the date to the right if you wish.

2. Opening salutation• Write the title and last name of the addressee (exclude the first name); for example, “Professor Brown” or “Dr.
Baker” (British English: “Dr Baker”).

••

If you can’t find a named editor on the journal website, then you can use the opening salutation “Dear Editor”.
At the end of the opening salutation, you can use a comma or a colon; that is, “Dear Dr. Baker,” or “Dear Dr. Baker:”(British English uses the comma; American English uses either, but the colon is considered more formal).

3. Purpose statement and administrative information• Clearly state the purpose of your letter (that you are submitting a manuscript) and then state your manuscript title,author names (or first author “Brown et al.”), and article type (e.g., original paper).

•Be sure to use the journal’s own terminology to refer to the article type; for example, some journals use the term
“Regular Articles” for a full research paper, whereas others use “Original Submissions”, “Full Papers”, “OriginalArticles”, among others.

••

See the downloadable Word template for an example sentence that presents this information clearly and concisely.
If your submission consists of many files, consider summarizing them in one short sentence so that the journal
editor is sure all of the files have been received; for example, “There are 8 files in all: 1 main manuscript file, 1highlights file, 3 figure files, 1 table file, 1 supplementary data file, and 1 supplementary figures file”.

4. Summary of main research findings and implications• In a new paragraph, summarize the purpose of your research (the research gap or problem it addresses), the main

findings, and finally the implications of these findings. This is your main chance to highlight the value of your work tothe journal editor, so keep this short and focused. (Journal editors may receive thousands of submissions annually,
and many fulfill editing duties on top of their own research and teaching schedule, so you should strive to make theirjobs easier by providing as concise a summary as possible.)•Be sure to tailor your statements so that they’re in line with the readership of the journal. For example, if you aresubmitting to a more general journal that has a diverse readership, underscore the possible impact your findings
could have in multiple fields. Conversely, if you are submitting to a publication with narrow scope, you can write
about your findings in highly focused terms.

•Avoid simply reproducing sentences verbatim from the abstract—which the journal editor will likely read next.
Instead, if you take sentences from your abstract as a base to work from, then try to craft a much shorter summarythat clearly fits the journal’s focus and that highlights the implications of your work for the journal’s readers. In
fact, Nature guidelines state specifically to “avoid repeating information that is already present in the abstract andintroduction.”•When stating that you think your work is a good fit for the journal, be sure not to use exaggerated flattery. Avoid
using words like “esteemed” and “prestigious” to describe the journal: “We believe that these findings will be ofinterest to the readers of your esteemed/prestigious journal.”•It’s helpful to the journal editor to state if your work directly relates to a paper published by another author in thesame journal. Also, mention if your study closely relates to or extends your previously published work, so it is clear
why your submitted manuscript is novel or important enough to publish.

5. Statements or information required by the journal• In this new paragraph, provide any statements that the journal requires be included in your cover letter. Be sure toreview the journal’s guidelines to know what information you should provide.

•Some journals or publishers have very specific requirements. For example, PLOS requires that authors describe
any prior interactions with the journal in the cover letter, as well as suggest appropriate Academic Editors from thejournal’s editorial board to handle the submission.

•Some journals require that sentences are provided verbatim in the cover letter. The guidelines will tell you to copy
and paste the sentence provided in quotation marks into the cover letter. For example, Springer states that cover
letters should contain two specific sentences: “We confirm that this manuscript has not been published elsewhere
and is not under consideration by another journal” and “All authors have approved the manuscript and agree with its
submission to [insert the name of the target journal].”•Several statements pertaining to research and publication ethics are commonly required by journals across a broad
range of fields. These are given in our downloadable Word template. When using the template, you can retain thestatements in full, revise them slightly as appropriate to your circumstances, replace them with any similar wording
required by the journal, or delete them if they do not fit your specific situation.

6. Closing salutation and your contact information• Briefly thank the journal editor for considering the manuscript and follow this with the full contact information of

the corresponding author (name, academic degrees or professional qualifications; affiliation and postal address;
telephone (and fax); email).

•Be sure to maintain a collegial tone to leave the journal editor with the best impression as he or she finishes reading
your cover letter and moves on to evaluate your manuscript.

•Avoid statements that could be construed as presuming to give instructions to the editor. For example, “we lookforward to your review of our manuscript” implicitly directs the editor to review your paper. Also, “[we look forward tohearing from you] at your earliest convenience/as soon as possible” implicitly directs the editor to communicate withyou quickly; instead, simply use a neutral but polite phrase such as “we look forward to hearing from you” or “welook forward to hearing from you in due course”.

•A suitable closing salutation is “Sincerely,” or “Yours sincerely,”
