here, Google is playing the role of both the seller (including links to places to purchase the book) and the library, since the copies being used are already purchased, as you point out. Anything that provodes MORE access to information will lead to increased sales for more obscure books, if it's something I'm not going to find on my own, making a snippet relevant to my search will make me more likely to discover the book. Thus leading to more sales, if the work is any good.
