I feel the need to mention here that I tend to go out and purchase books that I have originally checked out on library loan ~~when the book is so well written that I want to own it and read it over and over again~~
(That is my impulse toward music I find on the web, and also toward software. If the author is generous enough to provide a FULLY functional demo version, that is not ADware, for a limited time period, I will normally purchase that software IF it meets my needs and functions as predicted on my system.)
I'm sure I'm not alone in this. So as far as I'm concerned, the Libraries are responsible for increased sales!
