Free public access to United States government documents in a federal depository library is guaranteed by law (44 USC §1911). While UC Berkeley houses one of the most comprehensive collections of U.S. government documents in the country, the Library is one of over a thousand Federal Depository Libraries across the United States, and one of several Federal Depository Libraries in the San Francisco Bay Area.
The Current Population Survey (CPS) is one of the oldest, largest, and most well-recognized surveys in the United States and provides information on employment, earnings, and education. The CPS has been done by the Census and Department of Labor since the 1940's (earlier reports done by the Department of Labor go back to the 1930's). Sometimes, the older reports are called "Special Census." Also be sure to check out the various supplements done each month.
