Other Library Catalogs
Boston Public Library
The BPL is located two blocks from Commonwealth, and many students find it an invaluable research resource. You can access its catalog here. Additionally, you can access the Commonwealth Catalog (not to be confused with the Commonwealth School Catalog!) using your BPL account and search for hard-to-find books in libraries across the state.
Please see Ms. Johnson for more information about using the Athenaeum. The library uses both the Library of Congress system and the retired Cutter Classification System.
