This collection includes over 200 videotapes and audio recordings from the history of Cyan and the Myst series. The videos are primarily from the production of Riven: The Sequel to Myst, including raw camera footage and composite tests from the filming of the live-action portions of the game, developer interviews, and behind-the-scenes footage used in "The Making of Riven" documentary. The tapes also include footage from other Myst-related projects, along with footage from general Cyan history, such as news appearances and industry presentations.

Several tapes also include footage of other video games released during the time Riven was development, presumably from Cyan's market research. Some videos that were irrelevant to the history of Cyan were digitized but omitted from this collection.
