As a consequence of the 2008 NIH Public Access Policy, all peer-reviewed scholarly publications that are the result of NIH awards are required to be made publicly-available in PubMed Central. The major change to this policy that will go into effect on October 1, 2025 is that these publications can no longer be embargoed for up to a year after publication. These publications are required to be made available immediately.
As a result of the 2023 NIH Data Management and Sharing (DMS) Policy, scientific data that are the result of NIH funds are to be made publicly-available (as appropriate) either at the time of publication or by the end of the grant performance period, whichever comes first. For the most part, the NIH has not needed to modify or update their 2023 DMS Policy in response to the 2022 Nelson Memo. Their policy meets the requirements for the public access of data established in the Memo.
Please visit the 2023 NIH Data Management and Sharing Policy LibGuide for detailed information about this policy.
Publications: When a publication is deposited into PubMed Central, the National Library of Medicine (NLM) already has a system in place to collect metadata and assign a persistent identifier (PID) to each article.
Scientific Data: As part of the 2023 NIH Data Management and Sharing Policy, researchers are required to follow specific guidelines when depositing their scientific data into repositories to ensure that they are findable through reliable persistent identifiers like a DOI.
Researcher Digital Persistent Identifier: In 2019, the NIH began requiring all researchers supported by federal funds to obtain an ORCID, which is a researcher digital persistent identifier.
PIDs for Grants & Awards: The NIH currently assigns a unique identifying number to all grants and awards. However, the agency recognizes in the 2023 Request for Information in response to the Nelson Memo that "they are not registered or indexed to ensure uniqueness beyond NIH and they are not retrievable using a standardized communications protocol that would allow for interoperability". In other words, the current system for identifying grant numbers within the NIH does not meet the standards to persistently identify grants. Consequently, the NIH is exploring assigning a digital object identifier (DOI) system to grants and awards to address this issue.
The NIH will provide an update to their Public Access Policy with regards to metadata and PIDs no later than December 31, 2024.
