ISBN barcode changes

In January 2007 the US ISBN Agency began assigning 13-digit identifiers to books and book-related products. These identifiers, "ISBN-13s", incorporate the existing Bookland EAN into a new book identifier where the prefix can be either '978' (the pre-2007 current value) or '979'.

   ISBN-13

dLSoft Barcode components will automatically recognize ISBN-13 barcode data starting with 978 or 979 and generate the appropriate ISBN-13 barcode.

dLSoft Barcode components will generate ISBN-13 barcodes using the ‘978’ prefix from data supplied as the ISBN 10 data, if the EXTRA1 property is set to TRUE; otherwise it will generate an ISBN-10 barcode as before.

ISBN with 2 and 5 digit supplementaries are supported by some dLSoft products. The supplementary characters must be separated from the ISBN numbers with a / character.
