The NSF Public Access Repository (NSF-PARBETA) contains an initial collection of journal publications and the final accepted version of the peer-reviewed manuscript or the version of record as a demonstration of its functionality and eventual expanded content. To do this, the NSF system draws upon services provided by the publisher community including CHORUS (Clearinghouse for Open Research of the United States), Crossref, and International Standard Serial Number (ISSN). Over the next year, additional metadata and links to articles will be added as they are submitted to NSF, with anticipated annual growth of 40,000 publicly-accessible articles and manuscripts. When NSF-PAR moves beyond the "beta" period, it will offer distributed full-text access to all NSF-affiliated accepted manuscripts or articles after an embargo, or administrative interval, of 12 months.
