Amazon.com’s recent extensions of its “Search Inside the Book” feature:

“Amazon.com (Nasdaq: AMZN) today announced two innovative programs to benefit readers, authors and publishers. Building on its successful Search Inside the Book technology, which allows customers to search the complete interior text of hundreds of thousands of books, the company is currently developing two new programs that will enable customers to purchase online access to any page, section, or chapter of a book, as well as the book in its entirety.
     The first program, Amazon Pages, will ‘un-bundle’ the physical-world experience of buying and reading a book so that customers can simply and inexpensively purchase and read online just the pages they need. For example, an entrepreneur interested in marketing his or her business could purchase the relevant chapters from several best-selling business books.
     The second program, Amazon Upgrade, will allow customers to ‘upgrade’ their purchase of a physical book on Amazon.com to include complete online access.” (from 2005 )
