The Hillsborough County main library in downtown Tampa has the 1885, 1935 and 1945 state censuses on microfilm. It also has the index to the 1885 census. There are 30 rolls in the 1935 census and 43 rolls for the 1945 census, In addition they have the soundexes for the 1880, 1900, 1910 and 1920 federal censuses. They have started adding soundexes for other states, including Ga., Al., NY, Mass and a couple of others that I don't remember. You can search their holdings though their web page. I think it's www.thpl.lib.fl.us, or you can search for it by the phrase "Suncoast Free Net". Hope this helps.
