Fonds consists of records created or accumulated by Gladys Maria Hindmarch, primarily through her activities as a writer. Records document the writing and editing of her books and works of short prose, her other editorial work, and her personal and professional relationships with friends and other writers. Records include correspondence, drafts, manuscripts, notes, journals, published articles and reviews, and research records.
Fonds has been arranged into the following five series: Correspondence (1959-1998), Writings and related records ([ca. 1959]-1994), Notebooks (1962-[ca. 1981]), Works of others ([ca. 1959]-1997), and Personal records ([ca. 1962]-1985).
