Libraries Suwannee County is served by the Suwannee River Regional Library System, which contains eight branches and also serves Hamilton and Madison counties. Branford Dowling Park Greenville Jasper Jennings Lee Live Oak Madison White Springs Suwannee River Regional Library was first formed by a contractual agreement between Suwannee and Lafayette counties, making it the first regional library in Florida. In 1957, the local Library Board learned that they might get a grant for a new library if they joined with another county. The Suwannee Board convinced the Mayo Woman's Club in Lafayette County to have their county join with Suwannee County and organize the first library region in Florida. With the formation of the duo-county, Suwannee-Lafayette Library Region, it immediately received $28,224 in funds. A small library was established at Mayo in Lafayette County in October 1957. The library started as a 3,100 book collection but soon grew to some 10,000 titles, some loaned from the State Library. A bookmobile was also added and put on the road. After being successful with its new library, the Suwannee River Regional Library System was approached by a number of nearby counties interested in the project, and in 1959 Columbia, Gilchrist, Hamilton, Madison and Taylor counties qualified for membership and became a part of the system. Greenville, Jasper, Lake City, Madison, and Perry had small libraries operated by a Woman's Club that were also absorbed into the organization. By 1960, the library system now had 23,500 books in its collection, 3,000 of which were a gift from the Miami Public Library. On August 2 of that year, Dixie County became the last one to be invited to join in. Later, the Cross City library observed its official opening December 1,
