- In 1968, a system was establised to identify books and other publications. The ISBN (International Standard Book Number) system uses the ISBN to track books. The ISBN number is a set of number and or letters, separated by hyphens. It is usually on the back cover near the bar code.
- If you know the ISBN number for the book you will need for a college class, it will make the online search much quicker. Most on-line bookstores will let you search by ISBN number. This will ensure that you get the correct book, as each edition of a book has a different ISBN number.
- If you don't know the ISBN number for the book you will need, simply ask the professor. Many times they will list the ISBN number right on the class syllabus. If the professor doesn't know the ISBN number, simply stop by the college bookstore and look on the book.
