Where did you hear that?
Code:
The International Standard Book Number (ISBN) evolved from the Standard Book Number (SBN) previously used in some English speaking countries. An SBN is converted to an ISBN by prepending a digit '0'. Prior to January 1, 2007 books were published using ISBN-10, a 9-digit number plus one check digit. New books now are assigned an ISBN-13 number. Under the old ISBN-10 system, the ISBN number was used to make a number that could be encoded into an Bookland EAN barcode. Under the new ISBN-13 number, the ISBN and the Bookland EAN number is the same.
ISBN(-10) has check digits 0-9 and X (Mod 11) which did not convert to an all numeric UPC/EAN code
ISBN-13 codes start with 978+the ISBN-10 (sans the check character) and a EAN computed check digit
