My favorite hobby -- after reading true crime books -- is reading old newspapers. The language of old journalism is indescribable. The NewspaperARCHIVE website, a massive collection of old newspapers, digitized and text-searchable, knocks even my favorite slang site, AmeriSpeak: The Expressions of Our Ancestors right on its old kiester.
Last year, the Library of Congress in Washington thrilled the ten people in America who follow such things when it announced that it was creating an online database of historic newspapers, to be unveiled in 2006. Well, folks, it seems our gub'mint is about as useful as dried spit as it is now June of oh-six, and our Library hasn't even gotten around to writing down which historical newspapers it has! As of today, the library's website states that its list of US newspaper microfilm holdings from 1801-1939 is "Under construction."
If you like to buy, sell, preserve, and respect old newspapers, or even if you've never heard of anyone who buys, sells, preserves, and respects old newspapers, check out The History Buff, an antique newspaper dealer who affirms the ancient adage that content is king. It looks like he's a true crime buff, too. His website includes several articles on the subject. You might specifically enjoy --
-- The Jack the Ripper page, where the History Buff has e-published full-text reprintings of the actual news reports on Jack the Ripper from 1888 issues of The London Times.
-- The Bonnie and Clyde Page, where the History Buff offers full-transcript coverage of The Dallas Morning News and the seven articles it reported on the day the infamous spree murderers Clyde Barrow and Bonnie Parker were shot down like the crazy homicidal maniacs they were in May, 1934.
