ACS will deposit the final published article into the PubMed Central (PMC) repository for authors who participate in any ACS AuthorChoice program; authors must identify where deposits should be made, instructions are here http://pubs.acs.org/page/certified_deposit.html. Authors who are funded by NIH, Wellcome Trust, European Research Councils, or Austrian Science Fund and who select any ACS AuthorChoice option will have their articles deposited to PMC with no further actions required on the authors’ part. Deposits are subject to PMC’s deposit criteria–i.e. PMC does not accept deposits in subject areas that it does not cover. Authors who do not wish to participate in ACS AuthorChoice may self-archive the accepted manuscript version of their article for access 12 months after first publication.
