The fonds consists of a variety of materials, but the focus is the creative writing of Bullock, in many genres. Represented in collections are prose and poetry, both published and unpublished, along with hundreds of individual works, covering not only poetry and prose poems, but academic essays, autobiographical accounts, and plays, as well as a prodigious amount of notes. The fonds also contains material relating to Bullocks work as a translator and includes a variety of genres translated into English from the original French, German, or Italian. The fonds also includes correspondence of both a professional and personal nature. The correspondence from 1935 illustrates the business life of a professional writer; it also contains a wealth of personal correspondence that helps solidify Bullock's stature as a writer both locally and internationally. Impressive figures such as Marcel Bealu, Max Frisch, and Joy Kogawa are intermingled with less well-known artists, friends, and family in the correspondence, and provide valuable commentary, over nearly 70 years, into the creative path chosen by Bullock.
The fonds consists of 20 series and a single sub-series: Assorted Poems Series, Collected Poems Series, Prose Series (Lotte Bullock Sub-Series), Plays Series, Essays and Criticism Series, Artwork Series, Works in Translation Series, Correspondence Series, Notes Series, Reviews Series, Melmoth Vancouver Series, Photographs Series, Audiotape Recordings Series, Diaries Series, Biographical Notes Series, Conferences, Lectures, and Readings Series, Promotional Material Series, Financial Records Series, Published Material Series, and Miscellaneous Series.
