Historical Business Directories

Included in Contra Costa County Library's Vault Collection at the Pleasant Hill Library are historical directories of local industries and manufacturers. These directories do not circulate.

Unlike city directories, which list businesses by street address, these industry directories only list businesses alphabetically by city.
