Probably one of the most valuable set of documents for tracking the history of the Department of Fish and Game, now the Department of Fish and Wildlife, is the California Fish and Game Commission Biennial Reports.
I used these documents extensively for research in developing the ongoing history of the law enforcement unit of the Department.
I have been able to find and post 40 of these documents. The cover the time frame from 1870 to 1958. That means that much of the more current history is still unavailable online.
The reports were generally issued in two year books, but not always. I am missing a few years and will keep searching for the rest. I am missing 1893-94, 1897-98, 1899-1900, 1901-1902, 1907-1908, 1913,1917,1933. I also have some combined reports that may cover some of the missing years noted above,
I recently received a note providing info on some missing reports from my list stating that the following years 1899-1900, 1901-1902, 1912-1914, 1916-1918 could be found online at: https://catalog.hathitrust.org/Record/100639581
