book, is generated from the ISBN for the book. Bar code
scanning is used in the U.S. by major bookstore chains for
book publications and book-related items.
When encoded in an EAN-13 bar code, the ISBN is preceded
by the digits 978 and the ISBN check-digit is not encoded.
Instead, an EAN-13 check digit is added to the end of the bar
code.
There can also be a five digit supplemental bar code
representing the book price. The supplemental number begins
with a 5 for US Dollars. For example, if the book price is
$16.95, the supplemental number is 51695. A supplemental
number of 90000 indicates that the book has no suggested
retail price. Supplemental numbers in the range 90001 to
98999 may be used by publishers for internal purposes.
Complimentary copies of books are marked 99991.
