Library Catalogs

Your C/W MARS library card gives you access to all member libraries in central and western Massachusetts.

You can also use your library card to search for and request items from all across the state via the Commonwealth Catalog.

Search the C/W MARS catalog for items at the Merrick Public Library and other participating libraries in central and western Massachusetts.

You can also sign into your account to renew or place holds on items, get reading recommendations, and more.

Or, search the catalog and place holds in the C/W MARS mobile app.

Download the C/W MARS app:

If you can't find what you're looking for in the C/W MARS catalog, you can try searching all libraries across the state in the Commonwealth Catalog.

Please note that Commonwealth Catalog requests will only be filled if the title is not in the C/W MARS catalog.

You should always search the C/W MARS catalog before searching the Commonwealth Catalog.
