We make it easy to sign up for a library card. If you do not have a CW Mars library card, and you live in Masschusetts, you can sign up for eCard here. 

The eCard can used to check out ebooks, e-audio, emagazines and more. 

Borrowing Physical Items

Please note ecards cannot be used to borrow physical items or place holds on phyisical items. Visit the library with a photo ID and we will upgrade you to a physical card. A physical card is required to checkout physical items (books, DVDs, etc.) from the library. 

Note: If you already have a CW Mars library card, you already have access to digital content on Libby.
