Yes, generally, the ISBN needs to match. It changes as versions are updated. Mine ended up renting many text books, worked well. (The one exception to this was some brand new versions were sometimes not available yet, through the rental co, were on backorder.) At the end, you mail it back. Some used texts were available in the bookstore, but you need to be early. Then their college started using a rental service, greatly simplified things. They could return books there, at semester end. The shop knew everything needed and pre-arranged. I bought them hs texts direct from the publisher and while it worked well, it was a pain to manage. Imo, you want as much one-stop shopping as you can. Of course, depending on your major, you may want/need to keep some. (责任编辑：) |
