Storrs Library cardholders are part of a larger library network, CW MARS, which allows Storrs Library cardholders to enjoy access to materials from Storrs Library and Central and Western Massachusetts. Storrs Library’s membership to CW MARS is the reason why Storrs Library cardholders can visit neighboring libraries and checkout materials using their Storrs Library card, negating the need to sign up for a library card at each library individually. To put it succinctly, Storrs Library cardholders are also considered CW MARS library cardholders.

Storrs Library is committed to providing stellar, personal service and understands that the changing landscape of eBooks can be hard to keep up with. Storrs Library staff is available to help and answer any of your questions about accessing eBooks and/or navigating our collections and/or services generally. If you are having trouble, please contact us over the phone or in person and we will be happy to help.
