Back in the mid 1980's the State Library received an NEA grant to survey libraries throughout the state to determine the newspaper holdings of each library and also to identify all the California newspapers at the State Library. They published two reports: Newspapers in California and Newspaper Holdings of the California State Library. These are both valuable resources to consult to determine where various historical newspaper holdings exist.
