The National Software Reference Library (NSRL) is in the midst of making the freely acquired software in our collection available to the public. The software titles are stored in Library of Congress Bagit format.

A CSV file is available, which is a slice of metadata from the publicly downloadable full NSRL SQLite database, as a convenience for browsing and searching. The CSV headers are:
"application_id","package_id","object_id","manufacturer_name","name_b64","application_name","name_b64-2","version","acquire_date","file_size","location"

Since the application name or manufacturer name may contain extended set characters, the original strings are provided in base-64 encoding.
The 27MB CSV file is found at https://s3.us-east-1.amazonaws.com/rds.nsrl.nist.gov/software/NSRL_free_bags.csv As of May 2025, 105831 applications are candidates to be released.

A 29MB HTML file is provided at https://s3.us-east-1.amazonaws.com/rds.nsrl.nist.gov/software/NSRL_free_bags.htm which lists only the 
application_id,manufacturer_name,application_name,version,acquire_date,file_size

but also contains the relative links to the LOC bags, for ease of download scripting.

Questions and feedback may be directed to nsrl@nist.gov
