This series of materials consists primarily of drafts of Mills' poetry and prose, as well as essay drafts, autobiographical pieces, short stories, reflections, a radio play script, fragments, notes, lists, and numerous drafts of correspondence. Some of these draft letters were addressed to Peter Quartermaine, Robin Crozier, Alan Halsey, Adrian Mitchell, Marjorie Perlof, Jonathan Williams, and Pia Simig, among several others. A small portion of the notes and fragments pertain to novel ideas that Mills was developing and researching. The essays pertain to the works of poets and artists (e.g. Ian Hamilton Finlay, Roy Fisher, David Prentice, and Peter Berry), as well as broader topics, such as the "world of little magazines." Additional materials pertaining to Mills' writing include mockups and layouts of works such as poetry booklets and maquettes, but most significantly the board mockups of "30 Signatures to Silver Catches" by Ian Hamilton Finlay, Margot Sandeman, and Stuart Mills, which Tarasque Press printed in 1971 and also likely put on exhibition. To a lesser extent, the series also contains drawings, paintings, and collages; a small amount of teaching notes; and material related to to Tarasque, Aggie Weston's, and Poet's Poems. Mills' drawing of the Tarasque bird that became the magazine's front cover design is in this series. Some of these publications-related materials include catalogue lists, a note to subscribers, and planning notes.
