Paid memberships apply to those who do not pay a Town of Prosper utility bill or the CPR/C48 (Prosper Town) tax. The cost is $50 per library cardholder annually. In-person membership renewal and payment are required annually. Identification requirements are the same for a resident. NEW card application is available via a 2-part process: 1. Online/Digital application submission (you can complete remotely or at the library) AND 2. In-Person registration completion at the library within 30 days of submitting the online application submittal. Online applications are for adult memberships only. Juveniles/children may be added at the time of registration completion at the library. Membership Renewals do not require a new application. Non-residents may pay the annual $50 membership fee with a check, cash, or credit card.
