Each entry bears a unique, sequential number at the beginning of the entry. This is the number referenced in the Index located at the end of the guide. The set of numbers which follows the entry number are collection identification numbers. Use these numbers to determine the location of a particular collection using the Location Key also at the end of the guide. Location and identification numbers are required when requesting the retrieval of photographs for research use.
Some subject terms are local in origin.
Photographs are black and white unless otherwise specified. Towards the end of most entries, the researcher will see a cross reference to other finding aids which either provide more extensive information about the collection described or about related records from the same state or local agency. Occasionally, references to restrictions concerning access are also found here. See the California State Archives for more information.
