The series consists of 10 bound volumes of letterpress copybooks. The “letterpress copybooks” are the earliest series of documents compiled in the operation of the Dean’s Office. Such books were first produced in a time before carbon copy paper was readily available, using a 19th-century technique whereby documents were handwritten or typed using special copy inks or ribbons, then moistened slightly and pressed against the thin tissue paper-like pages of the books, creating sometimes clear, but other times barely legible copies. All the letterpress copy volumes in this series were probably manufactured with paper covers (the pressure needed for copying the originals being achieved by rolling the books) and - six decades or more later, upon accessioning by the Library - were rebound with library-style buckram hard covers. All have handwritten indexes listing the names of correspondents in alphabetical order with corresponding page numbers. Some of the volumes also contain vouchers for payment for goods and services ordered by the Department and personnel pay lists, as well as various other documents concerning the operation of Washington University Hospital, St. Louis Children’s Hospital and the O’Fallon Dispensary. Many loose documents to be found inserted between the pages of the books. Probably included with the “transfer file” (for more concerning which, see Series 2), Accession 77-012. Volumes 1-10.
