The Commonwealth Catalog allows MBLN cardholders access collections at other libraries across Massachusetts. Once you request an item through the Commonwealth Catalog it will take a few days for your local library to receive it and notify you.
When you are finished with the Commonwealth Catalog items please return them to the library where they were picked up.
Please search the MBLN catalog before requesting material from the Commonwealth Catalog.
Please note: The Commonwealth Catalog will be unavailable from August 9-11, 2019 to accommodate a system upgrade.
