That is a really good idea. I wonder how the progress is. There was an interesting discussion at cnet.com recently about the growing popularity of e-books. I also found out that among various advantages of e-books, quite frequently they are free and easy to get. At some online shops the book itself is expensive, but a short review or an abstract is available. I used to buy a book review quite often before I figured out this issue and for many of my works it was enough to have only this abstract and not pay for the whole book. I was just wondering how would you take this issue? I'm pretty sure for more sales it is better not to leave abstracts for more than 200 words.
