Library History

100+ Years of Library Service in this Location!

J.N. League donated space in his store building for Upper Lake's first library in 1914. Upper Lake's Harriet Lee Hammond Library opened in 1916. Mrs. Hammond donated the building in memory of her husband, Charles Mifflin Hammond, who died in 1915. Amy Murdock and Lottie Mendenhall donated the land. The Upper Lake Women's Protective Club ran the library on donations and fundraisers until the 1940s when the library became a tax-funded operation. When the county library system formed in the 1970s, Upper Lake joined the system in 1975.
