helpful tips - isbn: international standard book number
the isbn is a unique, machine-readable identification number, which marks a book unmistakably. this universally recognized, 13-digit number is divided into the following five parts, each separated by a hyphen:
- “978” prefix;
- group or country identifier, which identifies national or geographic grouping of publishers;
- publisher identifier, which identifies a particular publisher within a group;
- title identifier, which identifies a particular title or edition of a title; and
- check digit, which validates the isbn.
an isbn should be assigned to each title. each format or binding (i.e. hardcover, paperback, cd, e-book, etc.) must have a separate isbn. a new isbn is required for a revised edition. once assigned, an isbn can never be reused.
