How do I find out the ISBN #'s of my textbooks if my school doesnt want to give it to me?

I'm going to attend Pace University and I know the books I'm going to need I just think that I can get them cheaper somewhere else|||Who are you asking? The school bookstore will usually be able to provide them to you. If they refuse, you can always ask to see the books, pretending you are going to buy them, then copy the number yourself from the back barcode. It will be a long number that starts with 978. Don't just buy them from the bookstore because it's convenient, you have a right to try and get them elsewhere.
