The California Newspaper Microfilm Archive (CNMA) is the single largest collection of newspaper microfilm for the Golden State. It comprises approximately 100,000 reels for titles published between 1846 and the present. It includes film that the CBSR acquired from Data MicroImaging Company, Custom Microfilm Systems, Inc., BMI Imaging Systems (aka Bay Microfilm, Inc.), Wave Publishing, and film provided by the California State Library. Part of the acquisition has been made possible through generous support from the Haynes Foundation, the Ahmanson Foundation, Rivera Library at the University of California, Riverside, and the California State Library.
