You may search by any one or combination of fields. A search for "hill" in the Publisher field will
return all results for both McGraw-Hill and Hillsford, amongst others.
A books' ISBN is the International Standard Book Number, an identifier for most every book published
listed on the back cover. It's the same for every unique book published; so if you need Financial
Accounting (3rd edition), you can search for that ISBN and be sure that it is different from the
ISBN for Financial Accounting (2nd edition). Often, the textbook ISBN is listed in your course outline.
