“What are we celebrating, exactly?”
Glad you asked.
Library folks are known for being, well, quiet so we’re using National Library Week as an opportunity to get loud about the Library. How it’s a magical third space. An enduring place for our community’s stories. A true sanctuary for everyone.
San Mateo Celebrates! amplifies what the Library does year-round, reminding us that when the Library thrives, so does our City.
The San Mateo Public Library | 55 West Third Avenue
