Any Massachusetts resident above age 5, may apply for a C/W Mars Library Card. West Springfield Public Library is a member of C/W Mars and may use other member library's cards. Therefore, you would not need a library card specifically for WSPL if you already have a card from another local library. Applicants for library cards must show proof of address and complete the card application. Patrons may borrow up to three items upon first use. The library card is then mailed to the patron and may be used at other area C/W Mars libraries.
