This will undoubtedly be making the rounds, if it hasn’t already, but The New Yorker has an article on Google Book Search that’s currently available online.
(The New Yorker, it is worth noting, is not committed to making its information universally accessible and useful, at least not unless you buy the Complete New Yorker DVDs. The magazine does not maintain an index of its articles on its website, and its indexing elsewhere has historically been somewhat sporadic. You can read more on the magazine’s indexing, or lack thereof, in the latest Ask the Librarians column at Emdashes, which is, to the best of my knowledge, a labor of love by a writer and New Yorker fan. I should note that, despite my snarky tone, I also am a fan of the magazine–I just wish they’d publish their past tables of contents online so I could remember what the hell issue I read, say, Calvin Trillin’s recently turned into a book piece about Alice. But of course then I’d have less reason to purchase the DVDs.)
