Amazon.com announced yesterday that they have made the entire text of 120,000 books searchable. This feature is automatic when you use their regular search. I have to wonder how much load it puts on their servers to search so much data on every query.
On the plus side, they’ve added a Search inside this book feature for individual books. This goes a long way toward making Amazon as useful as a real-world bookstore–you can search through a nonfiction book to see if it has what you need.
