Effective April 7, 2008 scientists whose research has been supported in whole or in part by direct funds from the National Institutes of Health (NIH) are required to comply with the NIH Public Access Policy, which "ensures that the public has access to the published results of NIH funded research to help advance science and improve human health."
Upon acceptance for publication of all peer-reviewed articles, authors now must deposit electronic copies of their final manuscripts to the National Library of Medicine's PubMedCentral (PMC) so that the research may be made available to the public no later than 12 months after publication.
The National Institutes of Health Public Access policy details page has helpful links about how to comply and includes pages for Deposit News & Updates (use a Grant Lookup Tool to find current grant numbers), the NIH Public Access FAQ, and a General Help page with QuickTime, PDF and screen-capture tutorials.
Our colleagues at the Case Cleveland Health Sciences Library have created a site for NIH Public Access Information. You'll find additional information and help specifically for Case researchers, including the copyright letter from the Provost.
This CHSL site includes help on locating PMCID numbers, slides & handouts from their presentation NIH Public Access and You, as well as screenshots for PMC Single Citation Matcher, information about new requirements in citing articles, and more, in their Health Sciences Library NIH Public Access Tip Sheet.
