It was not until 1886 that the Cazenovia Library Society was formed. Societies like it maintained their libraries “through membership, lending fees, and gifts”  In 1890 Robert J. Hubbard purchased and donated a house for the library's use. Built in the Greek Revival style, it had been built in 1830 for John Williams. The ground floor of the house served as the main library building until a modern extension was built in 1996. Robert J. Hubbard also donated his collection of souvenirs from his 1894 Grand Tour trip. One of the most notable artifacts he brought back was an ancient Egyptian mummy. Since 1985 the Cazenovia Public Library has served as a home to four library cats.
