The Advantage of E-books

The semester break has ended and another new challenges is on my way... Yesterday our department chairman told me to prepare myself in teaching Advanced AutoCADD in 3D! Oops I was quite hesitant! I've been teaching Basic AutoCADD for four years and learn only a few with 3D (self- help learning).. Well, it's got to be challenging. So I went to the bookstore to find new releases of AutoCADD books from AutoDesk company but to MY DISMAY there was no available!Good thing there was an internet and a search engine that is really helpful! I tried search pdf and voila! there's a lot of choices that we can take in different formats aside from pdf (ppt, doc, txt, rtf etc.) and we can also buy via online for real books. There were also e-books available which for me is very advantageous since you do not need space for the book on your shelves but rather just on your mobile usb! amazing isn't it?
