In the Spotlight

Library Infrastructure Grant Program

The budget signed by Gov. Newsom for the fiscal year beginning July 1, 2021 contains the single largest investment California has ever made in local libraries. Chief among the investments is $439 million in one-time funds to create an equity-focused grant program administered by the State Library to support life-safety and critical maintenance and facilities projects. A statement from the State Library about the program.

Value of California’s Public Libraries

The California State Library is exploring and demonstrating the value that public libraries provide to their communities and the people who invest in them through a project titled Measuring the Value of California’s Public Libraries. The project began in January 2017 and continues until June 2020.
