Author Manuscripts in PMC

PMC serves as the full-text repository for papers that fall under the public and open access policies of a number of organizations that support scientific research. These policies often require authors to deposit a copy of their peer-reviewed manuscript, as accepted for publication by a journal, in PMC. These articles are labeled “author manuscripts” in PMC and branded by funding organization or funder group (e.g., Europe PMC, Health Research Alliance) to distinguish them from the final published articles that constitute the larger portion of PMC.

What is the Author Manuscript?

For purposes of supporting funder policies in PMC, the author manuscript is the version of a paper that has been peer reviewed and accepted for publication by a journal. This version should include all changes made during the peer review process, as illustrated below. Preprint versions that have not undergone peer review and/or have not been accepted for publication in a journal are not eligible for deposit to PMC.


Author manuscripts that fall under the policies of the NIH or another US funder that has partnered with NLM are deposited to the NIH Manuscript Submission (NIHMS) system, typically in Word or PDF format, along with all referenced table, figure, and supplementary files.

Display of Author Manuscripts in PMC


Author manuscripts in PMC are clearly branded as such. In addition to identifying the paper as an author manuscript, the banner at the top of the display indicates the primary funding organization for the research. In the case of U.S. Department of Health and Human Services (HHS) branding, the funding may come from one or more of a number of operational divisions of HHS, including NIH, the Centers for Disease Control and Prevention (CDC), and the Food and Drug Administration (FDA). To view the specific funder for a given manuscript, click on the hyperlinked PMID and view the Grant Support section of the PubMed record.

Below the banner, the manuscript citation denotes that the paper is an “Author manuscript” in addition to the date the full text was made publicly available in PMC. The citation information also includes a reference to the published article. If the article includes a digital object identifier (DOI) or is from a journal that participates in NCBI's LinkOut service, then the reference to the published article is hyperlinked directly to the full text of the version of record at the journal website. As available, the link to the journal website is also included below the author information in the yellow box.

All author manuscripts include the corresponding PMCID, NIHMSID (or other manuscript ID), and PMID in the top right-hand corner of the display.

Policies and Submission Systems

NIH-funded author manuscripts have been deposited in PMC since 2005 via the NIH Manuscript Submission (NIHMS) system. Over time, additional agencies and organizations have established public access policies that also require deposit of funded, peer-reviewed manuscripts in PMC via NIHMS. A list of these funders is available on the NIHMS website.

Similar public or open access policies are also in place for papers supported by funding from agencies across Europe. Manuscripts supported by these funding agencies may be deposited through the Europe PMC plus.
