Florida Administrative Code research

This question comes up frequently enough: how to find older sections of the Florida Administrative Code (FAC)? Start by checking the history notes at the end of the text of the Florida Administrative Code. The FAC is on the web, but it is not "to be regarded as the official copy." The Florida Administrative Weekly (the Federal Register-like publication for the state level), is available on the web from 1999 to the present. For a handy guide to researching Florida administrative law see FSU's powerpoint: Florida Administrative Rules and Hearings.
