The collection consists of 169 paperback books featuring Lesbian themes.

During the post-war period, from the late 1940's to the 1960's, a significant amount of Lesbian material became available amidst the proliferation of popular fiction published as paperback originals (sometimes referred to as "pulp" fiction). Some authors represented in this collection are: Ann Bannon, Paula Christian, Valerie Taylor, Artemis Smith, Randy Salem, March Hastings, Gale Wilhelm, Marion Zimmer Bradley (writing under the names Lee Chapman and Miriam Gardner), and Marijane Meaker (writing under the names Ann Aldrich and Vin Packer).
