This series consists of drafts of Leoni's writings, together with relevant correspondence, notes, and research materials. The majority of the articles, essays, biographical sketches, and book reviews written under his Garde pseudonym were intended for publication by ONE. Many of the materials are stamped with the date of receipt by ONE and are accompanied by ONE's publications committee, recommending publication or rejection, suggesting that, like the Garde correspondence with ONE, they were added to the collection after its acquisition by ONE, from ONE's own files.
