Check out the redesigned Magic Footnotes. The site has been simplified and refocused. I plan on regularly posting bits of information I have run across while looking for something else. Much will be taken from historical newspapers and publications. I will also be posting information and tips on conducting on-line research. Do check out the updated article on historical newspaper databases.
Gary -- your list of historical newspapers is great. The Old Fulton site, specifically is an excellent resource for anyone who hasn't checked it out before. And even if you have -- I came across some new things since the last time I was there!
