If you are a Floridian, especially of you have roots here, you will be interested in the Florida Memory Project at http://floridamemory.com/
This site offers a wealth of information on Florida history and its people. Photographs, videos, articles, and documents are all part of what you get...for free.
Of special interest genealogically is the online document collection. It includes Spanish Land Grants and Florida Confederate Pension Application Files...all digitized. World War I draft cards are presented also, but not the images, just the transcriptions. Finding aids are also referenced such as guides to the state archives and the state library.
This site can be a goldmine. Check it out.
