Since Hopalong Cassidy and the Lone Ranger blazed their first trails on television in 1949, Westerns have been the genre of choice for 180 series through 1996. Some (Gunsmoke, Bonanza, and Maverick, for example) were classics; others, such as 26 Men and Shotgun Slade, were quickly forgotten.

From Adventures of Briscoe County, Jr., through Zorro and Son, this comprehensive reference work covers all 180 Western series. Each entry opens with a listing of the broadcast history of the series, including original network, day and time. This is followed by a listing of the regular cast members and a brief premise of the series. The individual episodes are then covered, with the title, original air date, leading guest stars and a brief synopsis given. An exhaustive index completes the work.
