ISBN
Overview
ISBN, the International Standard Book Number, is a numeric barcode symbology developed by Gordon Foster in 1966. The 10-digit ISBN format was originally invented by the International Organization for Standardization and was published in 1970 as international standard ISO2108. Based on the 9-digit SBN, it is mainly created to identify books. Typically, an ISBN is arranged to each edition and variation of a book. There were only 10 digits of an ISBN before 2007 if you allocated it, yet the number went up to 13 after January 1, 2007. There may be times when a book may appear without a printed ISBN if it is published privately or the author disobeys the usual ISBN procedure.
Publisher code
It is universally known that before a book is published, the publisher has to select the item number and then the national ISBN agency will allot the publisher number. Generally speaking, a book publisher is not allowed to assign an ISBN, nor is it proper for a book to display its number. Nevertheless, most book stores only deal with ISBN-bearing merchadise. The ISBN agency does not provide any free method of checking publisher codes. Different codes are assigned to different publishers depending on the books they are going to publish. There may be more than one group identifier used in a country, which may happen if a popular identifier has used all of its available numbers.
Errors in usage
As for the ISBN check digit, policies vary from publishers and libraries. There are times when some publishers fail to check the correspondence of a book title and most importantly its ISBN before the book is published. Book identification problems for libraries, readers and booksellers can be caused due to that failue. However, most booksellers display the book record for an ISBN that is invalid issued by the publisher. At the same time, some online book-ordering systems such as Taobao.com will not look for a book if an invalid ISBN is entered to its search engine.
