Bookland barcodes
Bookland barcodes are unique numbers that are printed on the covers of books. They contain the book's ISBN number and pricing information encoded using EAN 13 bar codes with a 5 digit supplementary code. (Note that a new ISBN numbering system was added in 2007 – see ISBN)
For a book with ISBN 1-234-5678-9 retailing at $19.95 in the US, the data to encode is generated by taking 978, followed by the ISBN number 12345678 (the last digit of the ISBN number is a check digit and is not included), followed by a currency digit (5 for US$) and a four digit price (51995), ie.
9781234567851995
These numbers may be entered in dLSoft products using the \ separator between the ISBN number and the supplementary, eg
1-2345-6789-0/51995
