NSF Public Access Initiative

The NSF Public Access Initiative (PAI) strives to make the outputs of scientific research funded by the National Science Foundation publicly available to the greatest extent and with the fewest constraints possible and consistent with law.

The program maintains the NSF Public Access Repository (NSF PAR), funds a variety of projects to advance the understanding public access broadly, and coordinates a wide variety of agency activities regarding public access. 

NSF Public Access Repository (NSF PAR)

  • The NSF PAR is a repository of peer-reviewed papers and other products of NSF-funded research. 
  • It enables NSF-funded investigators to ensure that these research products are accessible to the public.
  • The NSF PAR continues to grow in content year by year, and will continue to be enhanced with new features in future versions.  Statistics on PAR holdings and growth will soon be viewable. 
  • The NSF PAR is located at the URL: https://par.nsf.gov/
