Circular Logic is based on a series of nineteenth-century circulars housed in the Chicago, Burlington, and Quincy Railroad archive at the Newberry Library. Railroad managers routinely received circulars listing terminated employees and the reasons for their dismissal. The text for this book is taken directly from these lists, with the exception of employee names, which have been altered. A worker's name is printed on the verso of each spread with his job title on the recto, which folds out to reveal a silhouette representing him, alongside the reason for his dismissal. The cover depicts a CB&Q route map printed from polymer plates. The interior images are artistic representations based on anonymous nineteenth-century photographic portraits, and are printed from metal ornaments and polymer plates created from handcut rubylith negatives. The text is printed from handset Bulmer and Antique Condensed typefaces. Each book is bound in a paper case and housed in a three-flap portfolio.
