The Fresno County Public Library holds five atlases, dating from 1891 to circa 1940, which segment Fresno County by township
and range, illustrating individual parcels and labeling them with the owners names. Detailed city and town plats are also
found in the atlases, showing lots, blocks and additions, although individual property owners are omitted. Their value to
historians and genealogists is tremendous, but the limited availability of copies has hampered their overall usefulness. The
dates of original atlases held by the Library are 1891, 1907, 1909, 1920 and circa 1940; it also holds digital facsimiles
of atlases for 1911 and 1913.
