You mean other than the obvious? New textbooks are in an unmarked, undamaged condition. Used textbooks may have markings, may be worn but should have no missing pages. Used textbooks, if available, cost significantly less than new ones and are GST exempt. You’ll find all used books shelved with the new ones in alphabetical order. Look for the yellow USED sticker! If you don’t see any used versions of the textbook you need on the shelf, it means we do not currently have any in stock.
