Depositing Peer Reviewed Research Articles to Public Repositories
If your research article arose from research funded by the U.S. National Institutes of Health or the Wellcome Trust, we will submit on your behalf a PDF of the published version of your article to PubMed Central or Europe PubMed Central to be released six months after the article is published.
If your research article arose from research funded by another not-for-profit organization that requires authors to submit to a publicly available, not-for-profit repository (such as the National Library of Medicine’s PubMed Central), you have NEJM’s permission to submit a PDF of the published version of your article (as supplied by NEJM) on the following conditions:
- You request, and the not-for-profit repository agrees, that public release of the PDF will not occur until six (6) months after your article is published.
- To avoid confusion in the literature that might arise from multiple versions of the same article, you agree not to submit any version of your article, except the PDF from NEJM, to any publicly available repository.
