What are International Standard Book Numbers (ISBN)?
International Standard Book Numbers are assigned globally to unique content and delivery formats so that subject matter can be catalogued and retrieved easily by interested parties. All JEDlet tutorials have their own, unique ISBN code, allowing you to do a keyword search by number. JEDlet tutorials are available for free consultation at the National Library in Ottawa Canada. They are listed on the National Library of Canada’s content database that is circulated around the world. In this way, researchers and students can find appropriate subject matter content using these numbers.
