The Sid Sackson collection is essentially the complete professional archive of Sid Sackson. Materials in this collection include diaries, correspondence, game descriptions and rules, writings, publications, newspaper clippings, magazine clippings, and some photographs. This archival collection documents Sackson’s life and activities as a game designer, collector, consultant, and author during the 1960s through the 1990s. (Magazines and trade catalogs from Sackson have been transferred to the library’s holdings. Any published games or game prototypes that were donated to the museum with the Sackson material have been cataloged individually in the museum’s Argus database and are housed in museum collections’ storage.)

The Sid Sackson collection is arranged into four series, one of which has been further divided into subseries. The collection is housed in 48 archival document boxes.

Digitized diaries and related documentation can be accessed through The Sid Sackson Portal.
