it u required any precious book then go to google google books and read online free you can also buy full version..
very soon you will be labelled a anti-environmentalist ;( eBooks are the way to go. Buy a book reader and you can start reading with ease.. zoom, save, click for more info.. ( i agree with the fun factor of regular books, but time to change,. )
Got to be honest i much prefer a traditional paper based book any day of the week. Publishing online is just a cheap way for publsihers to save money as most people will print iformation like a book off, because it's too demanding on the eyes to stare at a screen for hours.
