San Mateo County Libraries welcome volunteers and appreciate their contributions of time and talent to assist library staff in delivering programs more efficiently and effectively. Volunteers contribute greatly to the San Mateo County Libraries and are involved in many facets of our work. A variety of assignments are available, including library ambassadors, tech support, homework support, Adult Literacy, Youth Services Book Club and more.

As a condition of volunteer service, San Mateo County Libraries conducts a criminal background check of all prospective volunteers over the age of 18. Interested volunteers will not be charged for this process but are expected to have clearance before the beginning of volunteer service. We appreciate your understanding and cooperation as we ensure our libraries are the safest place for all of our patrons.

For more information about the available assignments and volunteer schedules, please visit your library's volunteer page. You may also learn more about volunteering by reviewing the following application forms:
