The Internet offers access to incredible amounts of information, but a lot of information is missing because most books are not available on the Internet. Amazon.com is trying to solve this problem with a new feature called "Search Inside the Book," which allows you to search the text of more than 120,000 books. Gary Wolf explains how Search Inside the Book works and discusses other projects designed to bring books to the Internet in this article from Wired magazine. Steven Johnson also discusses Search Inside the Book in this Slate article.
