Mary, those are temporary files that are opened just for you, the rest of us can't see them. There ARE ways to do it ~~ I'll see what I can do in a bit. I had noticed the mention about John Fitch when I was researching the other stuff, but hadn't read it. (time out)
OK, try #1 didn't work. I did not look at EVERY character, but it appeared that my url was exactly like yours.
One more shot, but it looks a whole lot like the other two! I suppose if all else fails, just go to the link I put up earlier (it works!) and enter Robert Fitch as an exact phrase search term. I am sure that there IS a way to link to the documents themselves, but this way you get to use the LOC search engine to find anything else that your heart desires to know about. Want to see over 2,000 baseball cards pre 1914? They got 'em. Want to see 19th century books and periodicals? They got 'em, though that particular collection is just getting off the ground. Want to see first person narratives of the American South? Yep, they got those, too. Just go exploring and see what you come up with.
