What is 'Pubmed Central (PMC)'?
-
PubMed Central is the U.S. National Institutes of Health free digital archive of biomedical and life sciences journal literature. Much of the full-text content in PubMed Central is added by authors themselves or publishers.
-
What is 'PubMed'?
PubMed is the database of citations and abstracts to the biomedical and life sciences journal literature. The links in PubMed to the full-text literature are added by library staff. Much of that full-text content is provided by subscriptions paid for by the UW-Madison libraries.
What does 'embargo' mean?
The time period between when the manuscript in published and when it becomes publicly available in PubMed Central.
Does 'research report' include the progress reports and final wrap-up reports that we submit to NIH?
-
No. The research reports that are peer-reviewed and published in a journal must be submitted to PubMed Central. The progress reports that you send to NIH that include citations must have a PMCID reference number attached to those citations that represent articles that fall under the NIH policy.
Numbers: PMCID, NIHMSID, PMID, HHMIMSID
-
What is a PMCID?
-
A PMCID is a unique PubMed Central reference number, which is assigned to each full-text record made available in PubMed Central.
-
What is a NIHMSID?
- Before the full-text record appears (while a manuscript is still in preparation), PubMed Central gives the submission a different number, the National Institutes of Health Manuscript Submission ID (NIHMSID). Either the PMCID or the NIHMSID may be used on a grant application or progress report to demonstrate compliance with the NIH Public Access Policy. The PMCID, when available, is preferred.
-
What is a PMID?
-
The PubMed ID (PMID) identifies a citation record (rather than full-text) in the PubMed database. It is not evidence of compliance with the NIH Public Access Policy, because it does not identify a full-text submission of any kind.
-
What is a HHMIMSID?
-
The Howard Hughes Medical Institute Manuscript Submission ID (HHMIMSID) is the identification number given to an HHMI manuscript when it is submitted to PubMed Central. It should not be used to indicate compliance with the NIH Public Access Policy.
Do I have to find PMCIDs for all the articles cited in a grant submission, or just my own?
-
You don’t need to find PMCIDs for all articles in an NIH grant application, proposal or progress report. You only need to apply the PMCID for those articles that fall under the guidelines of the NIH policy.
Can PMC associate a single paper with more than one grant number?
-
Yes. In fact, you are asked to identify all NIH grants that apply to the final peer-reviewed manuscript when a submission is made.
How do I find an article's PMCID?
-
Search PubMedCentral for the article; the PMCID will be on the right near the top of the article's page. The PMCID can also be found in the citation record in PubMed. Feel free to ask a librarian to help.
-
If I find an article in PubMed Central but it doesn't have a PMCID, what should I do?
-
The NIHMSID, or NIH Manuscript Submission Identification Number, is an acceptable substitute if no PMCID can be located (The PMCID is applied at the time of publication.). The NIHMSID is also near the top of the article's page in PubMed Central. If you can find neither, feel free to ask a librarian to help!
-
What do you do if the PMCID has not been assigned yet?
-
If you or a third party has submitted a final peer-reviewed manuscript to the NIH manuscript submission system, a NIHMSID will be applied to that submission immediately. Use the NIHMSID in citations until the PMCID is available.
Example: Cerrato, A., et al., Genetic interactions between Drosophila melanogaster menin and Jun/Fos. Developmental Biology 2006 Oct 1; 298(1): 59-70. NIHMSID: NIHMS44135
If your final peer-reviewed manuscript is submitted by a publisher, a PMCID may not be assigned until several weeks after publication. During this time, please indicate compliance with the policy by indicating "PMC Journal - In Process".
Example: Sala-Torra, O., et al., Connective tissue growth factor (CTGF) expression and outcome in adult patients with acute lymphoblastic leukemia. Blood. 2007 April 1; 109(7): 3080-3083. PMCID: PMC Journal - In Process
-
Is a PMCID the same as a PMID (PubMed record ID number)?
No. Grant applications, proposals and progress reports must include PMCID, or if that is not available, NIHMSID. A PMID is not an allowable substitute.
Can I use EndNote or RefWorks to format citations in my grant applications and progress reports?
-
Yes. See the EndNote and RefWorks instructions developed by the Libraries.
Submission Process
If I see a link to the full-text of my article in PubMed, does that mean I have complied with the NIH Public Access Policy?
A full-text link that appears in PubMed may go to material that is not free. Such a link is not evidence by itself of compliance with the NIH Public Access Policy. Your article must appear in PubMed Central for you to comply with the policy.
If the publisher submits an article on the PI's behalf, does the PI still have to approve the PMC-formatted version?
It depends on the version deposited and Journal's agreement with NIH:
(1) If your journal deposits the final published article in PubMed Central and allows NIH to make it available to the public within 12 months of publication, you do not have to do anything to fulfill the submission requirement of the NIH Public Access Policy.
(2) If the journal deposits the final published article in PubMed Central, but delays its release to the public for more than 12 months after publication, you will have to deposit a copy of your manuscript yourself.
(3) If the journal only deposits a copy of your final peer-reviewed manuscript via the NIH Manuscript Submission system, you will still have to sign on to the NIH Manuscript Submission system to review and approve release of the article to PubMed Central.
-
Can I use eRA Commons to do the submission?
-
If you are an author/grant recipient, yes. If you are a third-party submitter, you must login through the myNCBI system access to NIHMS.
How many publishers submit to PMC on behalf of authors?
-
About 400, though the number is rising. See the NIH list of journals that submit articles to PubMed Central.
Sometimes articles change between accepted manuscript submission and publication. If this happens, do I have to resubmit the article to PMC?
-
No. The system does not allow a duplicate submission to be entered. If there are significant changes made to an article in the copyediting phase by the publisher, the PI may still have an opportunity to suggest small corrections to the submission during the approval process. Ask your librarian for help if you have questions.
Some journals submit their articles to PMC, but they do not ask the authors for NIH grant numbers (only for the fact that the research was NIH-funded). What am I supposed to do to associate NIH grant numbers with those?
-
If the publisher submits the final published article, the grant number does not have to be associated with it, so there is no problem. However, if the journal publisher submits the final peer-reviewed manuscript, the grant numbers are supposed to be associated with it, too. The author or a third party can access the NIH Manuscript Submission System and link the publisher-submitted manuscript to the appropriate NIH grant/award number.
Would it be all right to wait for proofs to submit an article to PMC, in order to ensure that PMC reflects changes made during the publication process?
The policy requires that the manuscript is submitted upon acceptance for publication. Once the manuscript is submitted, the PI is required to approve the submission and has the opportunity at that later time to make needed corrections to the submitted document.
-
Can a document be associated with more than one NIH grant number?
Yes.
If a document is submitted and associated with only one NIH grant number, but it is later discovered that it should have been associated with additional grant(s), can the record be corrected to add the additional grant numbers?
-
Yes, it is possible for additional grant numbers to be applied to a manuscript that has already been submitted to the system. NIH wants submitted manuscripts to have all of the grant numbers indicated that apply to that research.
If research was funded by both an NIH research grant and an NIH training grant, must the training grant number be associated with the document?
-
NIH requires that each submission of a final peer-reviewed manuscript indicate all NIH grants numbers that resulted in the research behind the manuscript.
Is there any cost to submit other than time?
No, although some publishers are offering the service for a fee. The Libraries will submit your article without cost to you.
Who and What
If I am a collaborator or consultant on the grant, but not the PI, do I have to submit?
The PI is responsible for seeing that all articles resulting from their NIH funding are submitted, but any of the authors of an article can do the submission, or it can be done for them by a publisher or other third party. It is the PI’s responsibility to approve all of the submissions of articles resulting from their NIH funding also.
Must I add my prior publications to PMC?
-
The Public Access Policy does not require retrospective submission of articles published prior to the policy's taking effect. Depending on copyright agreement with your publisher, you may submit those publications to PMC that resulted from funding by NIH if you wish. The Libraries are prepared to help you do so.
Can I use the publisher's typeset PDF?
If the publisher permits; most require the author’s final peer-reviewed manuscript.
What file formats may I submit to PMC?
-
Several, including Microsoft Word, Microsoft Excel, Microsoft PowerPoint, PDF, TIFF, JPG,and others.
Will PMC accept supplementary material? What if that material has not been peer-reviewed?
PMC does indeed accept supplementary material. Images and graphs that are part of the peer-reviewed article will appear on the article's page; other materials are linked to.
-
Please clarify the dates. Which publications do I have to submit to PMC?
-
Only those articles that are accepted for publication after April 7 2008 and are the result of grants that were active during the NIH FY08 (1 Oct 07 – 30 Sep 08) or signed on or after April 7, need to be submitted to PubMed Central. If it results from a grant signed 7 Apr 2008 or later, the policy applies. If the grant was active in FY08 but the article grew out of research conducted in an earlier grant year, the policy does not apply. However, authors are encouraged to submit such articles to PMC if the terms of their publication agreements permit.
As a PI should I change my procedure for tracking publications growing out of the grants I supervise?
-
You may want to. Some universities are setting up centralized systems to track these publications, but that is not something that is likely to work on this campus. It is possible that some departments may start tracking the publications of their PI’s and researchers depending on the size of the department. We will be interested in learning how different PIs end up handling this.
-
Does the NIH policy apply to grants covering training or infrastructure?
-
NIH's response, "The NIH Public Access Policy applies to all types of grants. The answer to your question depends on if the research reported in the paper arise from NIH direct funds." So, the NIH policy applies to all peer-reviewed articles that arise, in whole or in part, from direct costs (costs that can be specifically identified with a particular project or activity) funded by NIH.
Timing
What if I have a grant submission containing a citation for an article that is in PMC but still under review, or under publisher embargo?
-
PMC issues an interim number (NIHMSID, or NIH Manuscript Submission Identification Number) that can be used instead of the PMCID in grant submissions, applications, proposals, or progress reports if no PMCID is available.
If final publication is delayed, do we have to worry about setting the date of publication in PMC in order to respect a publisher's desired embargo period?
The embargo may be set for no more than 12 months in order to comply with the policy. Some publishers honor a shorter embargo period.
Do I have to track publication dates in order to respect a publisher's desired embargo period?
No. The NIH manuscript submission system will track the publication date and the submitted embargo period for you and will transfer files to PMC.
Some journals submit articles to PMC for authors, but they may not do so in a timely fashion. What should I do if delay by the publisher means that there is no PMCID or NIHMSID available for an article that I must cite in a grant application, proposal or progress report?
If your final peer-reviewed manuscript is submitted by a publisher, a PMCID may not be assigned until several weeks after publication. During this time, please indicate compliance with the policy by indicating "PMC Journal - In Process".
Example: Sala-Torra, O., et al., Connective tissue growth factor (CTGF) expression and outcome in adult patients with acute lymphoblastic leukemia. Blood. 2007 April 1; 109(7): 3080-3083. PMCID: PMC Journal - In Process
Publisher Relations
Are any publishers unwilling to publish (or prepared to reject) articles subject to this policy? Will they be amending their author instructions and copyright transfer agreements to help researchers comply with this policy? Will I have to withdraw an article from a journal that refuses to allow me to comply?
-
NIH recommends that "Authors should work with the publisher before any rights are transferred, to ensure that all conditions of the NIH Public Access Policy can be met." (FAQ #c4). If your publisher will not accept NIH mandated archiving, contact a member of our Scholarly Communications & Publishing Subgroup to work with your publisher. We have not yet encountered a publisher that was unwilling to comply with the NIH policy. There have been some publishers that were unaware of the policy and changed their policy and workflow to accommodate the NIH policy.
How do I find out what publisher policies are?
Check SHERPA RoMEO and read your publication agreements. If information is not available on the SHERPA website, it is helpful to check the publisher’s website as well. The Libraries are prepared to help you interpret the language in your copyright agreement or help you located needed information about a publisher complying with public access policies such as NIH.
Does the Office of Research and Sponsored Programs handle or oversee copyright-transfer agreements I sign with publishers?
No. Reading these agreements and amending them if necessary is the authors' responsibility. If you need help, the Libraries are prepared to assist.
-
What is the difference between the NIH suggested language and the CIC author’s addendum?
The CIC author’s addendum is intended to be appended to any publication agreement, and does not specifically mention NIH. Given that NIH compliance is mandated by law, publishers may be more receptive to the NIH language. However, if the publisher agrees to the CIC addendum, the author will have the right to submit the article to PMC, in compliance with the mandate.
What about presentations at society meetings, where the society journal (e.g. Annals of Surgery) has right of first refusal on a paper?
NIH recommends that "Authors should work with the publisher before any rights are transferred, to ensure that all conditions of the NIH Public Access Policy can be met." (FAQ #c4)
What should I do if the publisher has a click-through online copyright transfer agreement that does not allow for modification?
We will try to find out NIH’s recommendation. In the meantime, our suggestion (but we aren’t lawyers!) is that you click on through but follow up immediately with an email stating that the permission you just gave is subject to the following language: [and append suggested NIH language]. Retain a copy of this email for your records.
Do I have to document in any way that my manuscript has in fact been peer-reviewed?
No; adding the journal name is sufficient.
Will usage statistics for PMC articles be sent to the publisher of the journal where the article is eventually published?
-
There are no plans to do this automatically, although such statistics can be provided to authors. Interested journal publishers may want to work with PMC to see if this can be done.
Can a publisher’s Open Access fee be charged to the grant that funded the research?
-
The NIH FAQ states: “Yes. The NIH will reimburse publication costs, including author fees, for grants and contracts on three conditions: (1) such costs incurred are actual, allowable, and reasonable to advance the objectives of the award; (2) costs are charged consistently regardless of the source of support; (3) all other applicable rules on allowability of costs are met.”

Campus Library Policies & Questions
As more journal articles become available free via PMC, might the libraries charge for Library Express delivery of final articles published in journals not owned by campus libraries?
-
There has been no discussion of this possibility. While it is true that the libraries are allocating resources to help campus comply with this initiative, we are doing so because of its importance to our community of scholars and researchers.
