The International Standard Book Number (ISBN) is a number that uniquely identifies books and book-like products published internationally.

From January 2007, it changed from a 10 to a 13 digit number which corresponds to a book's relevant barcode number.

ISBN Format
The four parts of an ISBN are as follows:

• Group or country identifier which identifies a 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;
• Check digit is the single digit at the end of the ISBN which validates the ISBN.
