The Commonwealth Catalog is a secondary resource that allows library patrons access to libraries that hold unique collections that are not available in the CLAMS catalog.

The Commonwealth Catalog covers millions of titles at participating libraries across Massachusetts. Items requested through the Commonwealth Catalog will take a few days to reach the Nantucket Atheneum.  Nantucket Atheneum will notify you when your items are ready for pickup. Items must be returned to the Nantucket Atheneum.

Please search the CLAMS catalog first. If the material you want is not available in the CLAMS catalog, search the Commonwealth Catalog.
