Book excerpt: From the days of the Spanish colonial settlements until the last state census in 1945, a variety of censuses have been taken within the regions now comprising the modern state, from lists of Seminole War refugees to modern school censuses. This book is a one-stop guide to the colonial, territorial, and state censuses, along with their supplements and substitutes. Covering original documents along with indexes, abstracts, translations, transcriptions, extracts, periodical articles, and digitized or microfilmed documents, the guide describes each source and evaluates its usefulness to modern genealogical researchers.
