Youth Library Card
San Mateo County Libraries have eliminated daily late fees for materials checked out to children and teens effective July 1, 2016. In honor of this policy change, we partnered with four amazing California-based artists and illustrators (Lisa Brown, opens a new window, Joe Cepeda, opens a new window, Alina Chau, opens a new window, and Christian Robinson, opens a new window) to create some new beautifully designed youth library cards for children and teens to choose from.

Teacher Library Card
San Mateo County Libraries offer a special Teacher Card for teachers, home school educators, or daycare providers who live or work in our service area (see list of participating libraries) and who want a separate library card for classroom use only.
- No fines fees on SMCL materials (you will be responsible for lost or damaged items).
- Longer loans on materials used in the classroom (excludes holiday and high-demand material).
- Teacher Card library records to help keep classroom use materials separate from personal use items.
