NIH offers guidance on selecting a repository for interim research products including preprints.
The NIH strongly encourages interim research products arising from NIH funds to be deposited in repositories that ensure:
- Content is findable, accessible, interoperable and reusable (FAIR).
- Interim product metadata, including usage statistics, are open, and easy to access by machines and people (e.g. via application program interfaces).
- Content is easy to use by machines and people. This access is both a function of permission (e.g. use of Creative Commons licenses) and technology (e.g. application program interfaces).
- Policies about plagiarism, competing interests, misconduct and other hallmarks of reputable scholarly publishing are rigorous and transparent.
- Records of changes to the product are maintained, and users have clear ways to cite different versions of the product.
- Links to the published version, if available.
- A robust archiving strategy that ensures long-term preservation and access.
