Rockland residents, current Coast Guard members, or property owners are eligible for a free library card, as are Knox County kids (from birth) and teachers through 12th grade. Any non-resident may purchase a card, and summer visitors may purchase a temporary card for a three-month period. Library users must possess a card to enjoy some of the many library services offered. A photo ID and proof of current address are required to obtain a card. For more information, please visit our Library Card & Loan Policies page.
