What are a journals options for depositing articles in PubMed Central?
A journal has three options for depositing articles in PMC. All three require the completion of a formal participation agreement with NLM and the deposit of full-text XML and associated files for the final published version of the articles. The PMC participation agreements that correspond to these options are: • Full Participation: the journal commits to depositing the complete contents of each issue or volume, starting with a particular volume/issue or publication date. • NIH Portfolio: the journal commits to depositing all NIH-funded articles (as defined by the NIH Public Access Policy), starting with a particular volume/issue or publication date. The journal may choose to also deposit other, non-NIH-funded articles. • Selective Deposit: generally used by publishers who offer a hybrid publishing model, i.e., a traditional subcription-based journal in which only selected articles are made open access. These journals deposit just their open access articles in PMC.
