The XXX Filmography, 1968-1988 features more than 3,000 A to Z entries, covering the historic, artistic, and technical aspects of adult cinema from those years, including 35mm features, 16mm storefront features, and 8mm loops. It provides director, producer, cast, screenwriter, cinematographer, and composer listings, with a detailed synopsis for each film. Production company credits, release dates and running times are also given. A DVD appendix lists all titles currently available on DVD, and complete cast and director indexes make this work the most comprehensive guide to Golden Age triple-X films ever published.
