"Search Inside the Book"

Amazon.com introduced a new feature today, entitled "Search Inside the Book." Thanks to the diligent efforts of what one must presume are thousands of scanner-operating chimpanzees, Amazon now allows you to directly search the text of some 120,000 books, and allows the searcher to then view any of those 33 million pages.

For example, not only was I able to learn that the name "Clark Kent" appears in Michael Chabon's The Amazing Adventures of Kavalier and Clay, I am also able to view all four pages of the book on which the name appears (pp. 3, 120, 330, & 585).

Of course, it doesn't cover every book. I had no luck in finding "Aziraphale" from Neal Gaiman's Good Omens. But it's an amazing tool nonetheless.
