Users' guide to the San Francisco newspapers index
compiled by Richard Terry ; assisted by California Section staff, California State Library.
San Francisco Newspapers Index is made up of three interfiled indexes: 1. San Francisco Call, Jan. 1, 1904-August 31, 1913. 2. San Francisco Examiner, September 1, 1913-September 23, 1928. 3. San Francisco Chronicle, September 1, 1913-December 31, 1949.
The continuation of the index to the Chronicle is called the "San Francisco Chronicle Index," or just the "Chronicle Index."
