Where do we find the ISBN's of our books?

<p>I’m planning to buy my books by my own. Not by bookstore.
Where to we find out the ISBN’s of our books?
When I go to WebReg and I click the little book It only says the Price, the tritle of the book/workbook and the Availability but now ISBN’s!!!</p>

<p>HELP</p>

<p>I find those listing are generally descriptive enough. Usually it includes author and edition. I just do a little searching on Amazon, and so far I haven’t come to class with the wrong book.</p>
