This subseries contains game production materials that are on loan from Ken and Roberta Williams. These materials include game scripts, sketches, flow charts, vocabularies, drawings, and more. Of interest are the two binders (housed in Box 4) used extensively during the production of Sierra On-Line’s well-known King’s Quest VI and Phantasmagoria computer games. The production books have scripts, annotations, illustrations, and other notes on the filming and programming from these games. For more game-related materials, see also the Sierra On-Line collection housed in the International Center for the History of Electronic Games at The Strong.
