About Martinez Library

The Martinez Library, completed in 1941, is located in an historic downtown waterfront community that also hosts the county government center for Contra Costa County. The library houses a small historical collection that includes works by many famous local and state figures, including Martinez resident John Muir. Hanging in the library are portraits of Dr. and Mrs. John Strentzel, painted by Muir's friend and noted California artist William Keith. In addition to the historical, Martinez Library provides public internet computers, WIFI, a steady supply of new materials in various formats, and regular programming for children, teens, and adults. The library was renovated and expanded with funds from Measure H and re-opened on August 20, 2011.
