Due to the implementation of a new Collection Management System, CHM staff will not be able to assist researchers and in-person visits until March 2025.
From magnetic tape and rare film to lab notebooks and business plans to early mainframes and source code, our collection is as diverse as the history of computing. It is a rich resource for everyone, comprising historical objects, documents, software titles, ephemera, and photographs and moving images.
Note: CHM's online catalog has been updated through January 23rd, 2025. A new and improved catalog will be launched in Summer 2025.
