Coolness. Good advice. I have a list of phrases I check, such as "glass aggies". Well, not so much a list, as scattered notes with different phrases. [Edit: No, "glass aggies" didn't turn up any good results this time.]
What is it with 1922?
The New York Times also only goes up to 1922 for its free archives. And the LA Times also splits its archives after 1922. (I think it charges whether before that line or after, but they're two separate collections.)
At first, I thought that had something to do with copyrights expiring, which made me think that every year we'd get a new year of papers added to the free section, but the 1922 date has held steady at the New York Times since I first started checking it almost ten years ago.
