If a patron owes more than $10, their card is blocked from use. This includes using the Internet and checking out materials but does not block the use of the library catalog or using materials within the library. Expired cards are also blocked. Resident’s cards expire every three years and require the patron to update their current information yearly. Out of city cards expire after one year, and Texshare cards expire every three months. Cards may be updated at the library information desk as long as the patron shows photo ID.
