Arts and culture Janesville Public Library The Janesville Public Library was created in 1962 with the inspiration of Clark Corwin with help from Hattie Zo Shoesmith and Margaret Theis. The library started as an all volunteer and all donated materials library in a room located in the city hall. Arlene Warm volunteered her services as a librarian. In the late 1960s, the city council authorized a 200 dollar a year grant for the library. In 1973, the library received a $10,000 grant from the Kinney Lindstrom Foundation that had to be matched by the local public. These funds allowed the library to expand into a new area. the library has approximately 10,000 books, 55 magazine and newspaper subscriptions, 1,200 videos, 85 audio tapes, 6 computers for patron access, and offers audio book downloads. The library has an average of 1,000 patrons each month.
