Many bloggers have been taking advantage of the fact that Google has placed online 10 million photos from the files of LIFE magazine.
I was surprised and a bit disappointed when I first used the archive, because the search engine would only retrieve a maximum of 200 images for any request. I have subsequently discovered a way to circumvent that restriction.
A search for "Minnesota" retrieves the max 200 images. Many of those are of sports teams. So I redo the search and subtract "vikings" - it still retrieves 200 images. Subtract "Twins" - still 200. Subtract "university" - still 200.
It's the same for any broad search. "President" retrieves only 200, but "president source:life -eisenhower -kennedy -nixon -ford -truman" also retrieves 200 photos.
It's a way to dig deeper into their archives.
