This printed work is a house copy of Macmillan's catalog of books. The two bound volumes were originally published as one volume. This copy probably used by the royalty accounts department is interleaved with blanks pages following each printed leaf. Copious annotations and manuscript notes have been recorded on the blank leaves spanning the years from circa 1890 to 1920. Each item in the printed bibliography has a space and or notes on the added facing page. There are entries regarding payments to authors, editors, illustrators, and translators, changes in publishers, commissions, copyright expiration and renewal, profit percentages, royalties, and sales data. The dates recorded in the annotations refer to contemporary and historical information. Notes also appear in the index chiefly regarding authors. Lines divide each entry on the page.
