Built entirely on donations, the original seed collection was gifted to The Center in 1976 in memory of Terry Mangan, one of Colorado’s first gay activists and archivists. Terry Mangan founded the Gay Liberation Front and was the first coordinator of the Gay Coalition, a group established in Denver in 1973 to combat police harassment of gay men and lesbians. He also authored the book Colorado on Glass: Colorado’s First Half Century As Seen by the Camera; which was published in 1975.
From leisure-reading fiction to LGBT history and everything in between, The Terry Mangan Memorial Library houses a diverse collection of books, magazines, journals, and other materials. The library can be found on the first floor of The Center and is open to the public five days a week. All materials are available for circulation.
