Material documenting the production of Westall's longer published books. Files include preparatory notes, manuscript and typescript drafts, proofs and associated material. The series does not represent all of Westall's published books. Material relating to particular titles varies in quantity and may reflect different stages of the creative process, from manuscript drafts to annotated proofs. Material may also relate to separate editions of books; this has been noted when documents refer to anything other than the first edition. Later files frequently contain photocopies, faxes or other forms of facsimile, which may have one or more consecutive sets of manuscript editorial annotations and authorial revisions.
Since the series also represents material published after Westall's death, later files may contain original drafts by Westall and later revisions and related material created and compiled by Lindy McKinnel, Laura Cecil and various editors. Later files occasionally include related correspondence.
