The Demian Katz Gamebook Collection (Mss 294) is now open for research in the Department of Special Collections. This rare collection, a highly comprehensive resource for anyone interested in this once popular genre, consists of more than 2500 gamebooks (primarily paperback) along with works in other media, including magazines, software, films, comics, and audio recordings. Though a large portion of the gamebooks are in English, many other languages are represented in addition. The collection covers interactive books (branching-plot novels), solitaire role-playing with rule sets, and multi-player combat books. A guide to the collection may be found here.
