    The change to 13 digits was needed in order to expand the numbering capacity of the ISBN system and alleviate numbering shortages in certain areas of the world. Also, by changing the ISBN to 13 digits, the book industry has fully aligned the numbering system for books with the global GTIN identification system that is widely used to identify most other consumer goods worldwide.

    They're running out of 10 digit combinations, from what I've heard, so they need to extend the codes to 13 digits.

    It's just a guess but probably the same problem they had with 7 digit telephone numbers, forcing them to go to 10 digit, has happened with the ISBNs, i.e., they ran out of 10 digit combinations and needed to add three more digits to accommodate the world's ever-expanding literature.
