The Grosvenor [pronounced Grov-ner] houses the Special Collections department at the Central Library of the Buffalo & Erie County Public Library (B&ECPL). The nearly 500,000 titles of unique and varied materials support the five collections of Local History, Genealogy, Maps, Music and Rare Books. The department name comes from an early library benefactor, Seth Grosvenor (1786-1857), and benefits from the 1953 merger of the Grosvenor Research Library and the Buffalo Public Library collections.
