Local publications can be difficult to locate at times. The internet is providing more and more access to documents, but do not be surprised if what you are looking for is not readily availble.
If cannot locate the information online, try to locate the contact information for the city/county department that seems to relate to your issue and email or call them.
UF has some materials for various Florida counties. To determine what UF has collected, check the UF catalog.
If you cannot locate the information, contact the reference department of the library at (352)273-0723
