Papers include teaching and research materials, class reports, and other documentation collected by Mary Celestia Parler-Randolph, of the Department of English, University of Arkansas, Fayetteville in the course of her work with Ozark folklore, especially Ozark folksong. These materials were originally housed in the Department of English, as part of the Folklore Research Project files. The material was used to compile the twelve volumes of Arkansas Folklore in Special Collections that cover proverbs, riddles, beliefs, superstitions, as well as ballads contained in what is now known as the Mary Celestia Parler Ozark Folksong Collection. This collection contains professional correspondence, style sheets, and drafts of the bound non-song materials in the University Folklore Collection, audio recordings, class notes, student reports, photographs, and index cards pertaining to organization of the collection and contact organizations and individuals. Other materials include index cards of folk sayings and stories; audio reels of folk songs and folk stories; materials related to the Ozark Folklore Society; and writings of Mary Parler and of her mother, Josie Platt Parler.
