The International Standard Book Number (ISBN) is an international number specially used to identify books and other documents. ISO promulgated the ISBN international standard in 1972, and set up a management organization to implement the standard in Prussian Library in West Berlin. At present, publications using ISBN coding system include: books, pamphlets, microforms, Braille printed matter, etc.
ISBN number consists of 13 digits, separated by 5 connecting digits or 4 spaces, and each group of digits has a fixed meaning.
EAN: European commodity number. In 2004, ISBN Center decided to add a set of three digits in front of ISBN, that is, add the prefix number "978" or "979" to the existing 10 ISBN and recalculate the audit number to convert it into a new 13-digit format. The plan was implemented on June 65438+ 10/day, 2007.
