It's quite a risk to open up a book like this. More so if the main sales are expected to be E-versions.

I've talked to a few people who did things along this line, and they are of two minds. One camp says it kills sales. The other says it boosts sales, but in the latter case I don't think there was a PDF version even offered, and they made the book available as a Web site.

I encourage people who think this book is valuable to pay for it in some form, to encourage publishers to do more of the same, and to reward the author.
