WHEN AND WHY SHOULD YOU USE THE COMMONWEALTH CATALOG?


START LOCAL
Libraries share items across the state, but it’s always faster and more cost effective to check the catalog here in Bolton first.  If C/W MARS (our regional network) doesn’t have the item, it’s time to look in the Commonwealth Catalog!


MILLIONS OF ITEMS
The Commonwealth Catalog gives you access to millions of items from libraries that hold unique collections such as Boston Public Library and UMass Amherst or other academic, special and public libraries.

​​
CONVENIENCE
Once you request an item through the Commonwealth Catalog it usually only takes a few days for us to receive it. They’ll notify you automatically so you can stop by to pick it up. You can return items borrowed this way just as you would any other item.
