This bibliography is a comprehensive list of soil maps for California appearing in the Soil Survey Series of 1899 through 1962. �Though the Soil Survey Series
started in 1899, maps for California do not appear until the 1900 series, at which time the Fresno and Santa Ana sheets accompanied the soil survey reports with the same names. There were also no California maps issued in the final year covered, the 1962 series.
Map entries are arranged according to series chronology, i.e. the 1900 series maps first and the 1961 series maps last, and are numbered
1 to 105. Each entry includes the soil map title, names of those responsible
for the map content (i.e. those who did the actual field work), series
date, scale, date of aerial photograph
base map if applicable, soil report title, issue date, the SuDoc number
for the separate soil survey and/or field operations report, and in
parentheses the counties covered.
Two indexes are included, author and county/area name, correlated
to the bibliography by map entry numbers. The county /area name index is especially useful for finding maps for those areas not consistently contiguous with county boundaries, or those without a county name in their title. County entries are made If a sheet covers 20 or more square miles of any county, whether showing soil or only base map information.
