This subseries contains invoices for items sold by the Heritage Book Shop to other bookstores, libraries, universities, and individuals. The subseries also contains folders of consignment sale invoices, invoices from joint sales with E. Joseph Bookseller and James Cummins Bookseller, and other invoices. Not all years have a complete range of alphabetical files, and a few years are missing.

This subseries contains printed book descriptions used to describe a book's contents, appearance, and condition for use in selling rare books. The book descriptions are housed in folders titled by author's last name, subject, or general work title.
