Unbound page proofs of the volume (lacking the final page), date stamped 18 January 1974, and also stamped as passed for press with the date 26 January 1974 added in pencil. Schmidt has noted on the first sheet that these proofs are intended for final corrections and the set is also stamped as the reader's press proof'. A stage on from the collated proofs, these proofs have been revised to incorporate all the corrections made on the earlier set. They were originally divided into four bundles - three containing four signatures of the book and the final containing two (a note of this is made on the first sheet of each bundle). Only minor corrections have been made and each page has been ticked and crossed through when approved. Each section has been initialled, presumably by a reader at the printing house and noted or stamped with the date 29 January 1974.
