So, I just now was trying to find something by the philosopher Donald Davidson, and did a google search to that end; what google gave me was a scanned article in an issue of the Milwaukee Sentinel from 1947 (!), the keywords I’d entered (‘Davidson immortality’) highlighted in the graphic.
Has google always been able to do that, or is this a new capacity? I mean, I know about google books, but over 60-year old newspapers? How extensive is the archive it searches? Is there a way to exclusively search newspaper articles, like ‘newspaper:Milwaukee Sentinel’?
