"The Incredible Gladys Pyle" Collection consists of clippings, correspondence, financial records, manuscripts, research, transcripts and audio cassettes.

The clippings include advertisements for the published book and clippings of Gladys Pyle on her 96th birthday. The correspondence includes letters on the publication of the book and letters from Gladys Pyle noting corrections for the book. Included is a handwritten letter from Governor Sigurd Anderson praising Gladys Pyle and her contributions to South Dakota politics.

The financial records are minimal and include itemized lists of expenses. There are two manuscripts for the book, one is with the published title "The Incredible Gladys Pyle", and the other with an alternative title "Gladys Pyle: Always a Pioneer". The transcripts appear to accompany only one set of audiocassettes. Included with the transcripts are notebooks with interview questions for Miss Pyle.
