Located on the 9th floor of Memorial Library and accessible using elevator #5 (marked “Special Collections | South Stacks”), the Department of Special Collections contains manuscripts and rare books which benefit from special handling because of their age, rarity, or value. The Department also houses collections that are themselves of unique research value, because they concentrate on a particular author, publisher, topic, or genre and thereby permit scholars to explore a subject in great depth. The reference collection in the reading room is available for browsing; all other Special Collections materials will be paged and brought to researchers in the reading room. Special Collections materials do not circulate. Public patrons and researchers are all welcome to view the collections.
