Keep an eye on Jerry Reed's Free Genealogy blog. Last week he posted about a free online site, the Florida Digital Newspaper Library, housed at the University of Florida George A. Smathers Libraries, with 384 titles from portions of three centuries. These are actual full-page and fully searchable images. My only complaint is that the search function only takes you to the individual page and doesn't highlight the phrase sought. Those 19th-century papers packed a lot of print onto one page!
