Presence

This is nothing short of astounding.

Not only does their book search return books that match the search terms you are looking for, but within most books you can search on the full text, and Amazon returns for you the page number and context of the search terms.

Incredible.

I've been playing around with this Amazon thing some more. For those of you who are Amazon-philes, as I am, you will know that Amazon had a feature called "Look Inside the Book," where you could view the cover, table of contents, and usually a short excerpt. For books with "Search Inside the Book," it seems they have the entire text online, retrievable when you get a search hit on that page.

Phrase searching does not work.

More updates as they develop.
