This collection consists almost entirely of correspondence from Ray Bradbury regarding submissions and publishing during Bradbury's early career, 1939-1950s. Most of the letters were written to Erle Korshak, founder of Shasta Publishers, but some of the correspondence is both to and from Ted Dikty, Shasta's managing editor and a well-known SF anthologist.

There are a few later pieces of correspondence, dating from the 1980s.

This collection includes manuscripts, papers, and publications from throughout Mayhar's career, but the bulk of the material dates from the late 1980s to the present.

This collection contains manuscripts, printed material, correspondence, legal documents, financial documents, idea books, photographic material, and books created and/or maintained by Howard Waldrop which give a glimpse of his personal life as well as document his professional life as one of the prolific and best-known science fiction writers from Texas.

The first category consists of Howard Waldrop's works both published and unpublished arranged alphabetically by title. Some manuscript files in this category may contain correspondence, notes, research material, contracts, royalty statements, proofs, etc. Thus, information about a specific story can be found in the collection by title.

The second category consists of materials related to Waldrop personally and/or professionally. This category is arranged alphabetically by general topical heading. His idea for some of his stories can be found in his Idea Books file from 1968 to 1988. Information about him personally or professionally can be found in the newspaper clippings, correspondence, and his work diaries files. His movements for any given year from the 1970s to 1994 could be reconstructed from his science fiction convention, conferences, programs, etc. file. But the most important file in this category is his story logs file 1970-1989. The file shows: when and where a story was written, how long it is; who bought it or did not; when and where it was published (or supposed to be published); and any subsequent reprints or foreign editions, royalties, etc.

The last category of the collection is works by or materials related to other science fiction writers. It includes manuscripts of other writers' works that happened to be in his possession or other writers' manuscripts in which he is a collaborator. Some biographical sketches of other writers can be found in the Con Bios-writers file. Information about Waldrop written by other writers can also be found in this category of the collection.
