What Is San Mateo Celebrates?

San Mateo Celebrates! is a National Library Week festival on the San Francisco Peninsula — a week of programs, installations, performances, and public gatherings rooted in one place: the San Mateo Public Library Main Branch.

Less street fair and more a civic week of ideas, culture, and community storytelling, the festival invites guests to gather around the questions, histories, and innovations that shape our community.

A Place for Everyone’s Story.

This year the venue of our celebration, the Main Library, turns 20. For two decades, it has stood at the center of San Mateo, holding the everyday moments that shape a life: a first library card, a quiet room when focus was needed, somewhere for children to discover and grow, the resource or guidance that made all the difference.

Our theme this year, A Place for Everyone’s Story, honors the role the Library plays as a shared civic space where individual lives and community history meet.
