Selection of Materials

Library materials are designated for IGRA when their subject matter, format, age, scarcity, or other unusual characteristic merits their inclusion. The Head of Special Collections & Archives determines what materials shall be placed in IGRA. The librarian may also confer with members of the Library faculty regarding the transfer of items already in the collection that meet these criteria, and for the purchase of new materials.
