Something I found today while looking up something else:
Paper of Record.
This is an ambitious project which seeks to create an archive on the world wide web for researching news stories that predate the internet era:
Paper of Record is an historical archive of full-page newspaper images that you can search for unique coverage of past events. The archive is created from newspaper collections on microfilm, preserving the original format of the paper, but saving you hours, even days, of research time. Now, you don't have to scroll manually through reel after reel of film to unfold history, page by page.
That's right, a vast microfilm archive as close as your keyboard. More than a million pages are already available, with hundreds of thousands more promised soon.
