I was researching the 1899 New York City Newsies' Strike (the one that Newsies is based on). I thought it would be cool to see what reporters at the New York World thought of the strike, so I was trying to find issues of the World from July and August 1899. I looked for like an hour, before I realized...
1899 pre-dates the internet. Which means that any news articles from before the 1990s had to be saved in hard copy long enough to be uploaded when the internet was invented. Well, the New York World had a morning and evening edition. That's two papers a day for almost 100 years. That's a lot of paper to just have laying around. Of course the New York World didn't save it! The New York World also folded in the 1960s, with no reason to believe that 30 years later, something called the internet would be invented and their pile of newspapers would have a place to go.
So then I thought. Well maybe a private citizen could have saved their copy, so I kept looking for a copy of the World from July-August 1899. Until I realized.
In order for a private citizen to save a copy of the New York World, they first had to buy a copy...from a Newsy. There are no copies of the New York World from the Newsies' Strike because no one could buy a copy from a Newsy, because the Newsies WERE ON STRIKE.
