They both have interlibrary loan ILL I suspect but the libraries they use primarily for it fan to the east for Lake County http://lakeline.lib.fl.us/programs_a...braryloan.aspx and to the west for Sumter County http://sumtercountyfl.gov/libraries/index.htm From my searches for materials where you do not have to put in an ILL request, Lake County Library system has a great deal more in its system than Sumter County has.
