The series is divided into two subseries, Textual Materials and Electronic Backups. Textual materials consist of manuscripts of novels and short stories. The arrangement, primarily chronological by published work, also reflects two peculiarities of his writing style. First, he labelled some as the final draft prematurely rather than numbering successive drafts. Some of his novels, therefore, have several "final" drafts. As best as possible, these have been arranged in chronological order. Also, during the creative process and modification of draft versions, Maillard created what he calls "spin-off," including ideas that are developed on the side but never added into storyboards developing the arrangement of the scenes and pages removed from a draft version. Other segments of the spin-off are unidentifiable beyond the novel to which they belong; these have been given a letter designation (A, B, C) to indicate which files were found together. The letter does not imply any sense of order, chronological or otherwise. Spin-offs with uncertain chronology have been filed at the end of each manuscript sub-series with specific research notes and related miscellaneous files. Some files contain UBC-related correspondence. The electronic backup consists of copies of the textual materials.
