This collection consists of various correspondence, photographs, short handwritten manuscripts, and oral history communications with transcripts describing Ava Johnson's life, and work as a women cattle ranger in Texas.

The collection was compiled by Cynthia Ott, who interviewed Ava Johnson Cox with the intent of publishing a history of early 20th-century life in what is known as the Hill Country of Texas (highlighting Blanco, Gillespie, and Hays counties).

This collection consists of 81 leaves of uncorrected galley proofs for Williamson's 1975 collection The Early Williamson.

This collection consists of two typescripts from the acclaimed science fiction author Edward Bryant (1945-2017). The materials include a photocopied typescript of Bryant's 1984 story "Dancing Chickens", with edits; and the first four chapters of an unpublished novel by Bryant, No Limits. The chapters also contain handwritten edits from Bryant.
