The Cabrinety Project is a large-scale digital preservation effort between Stanford University Libraries and the National Institute of Standards and Technology to create forensic disk images and photographic scans of materials in the software series of the Stephen Cabrinety Collection in the History of Microcomputing. My task was to assist with digital preservation by sending out permission agreements for the digital software items in the collection. I identified rights holders for the 8,000+ items in the collection, sent permission agreements, and then based off their response, determined the level of access each digital item will have in the collection.
