ISBN
The older ISBN-10 coding scheme is EAN13, with the first three digits being 978 or 979, and 9 digits the ISBN number of the book (without check digit). The final digit is the EAN calculated check digit.
Users can produce the ISBN barcode by selecting EAN-13 as the barcode type and entering the EAN number. Alternatively the ISBN barcode complete with the ISBN text above the barcode may be obtained by selecting ISBN as the barcode type and entering the ISBN 9 or 10 digit ISBN value (which may include dashes, eg. 1-2345-6789-1). The barcode image which results is as shown below.
ISBN
Note that the final digit of a 10 digit ISBN number is an ISBN check digit and this is NOT included in the barcode image. The barcode image will contain the EAN check digit.
The spacing of the text above the barcode may be modified by entering a character spacing value between 50 and 100%.
From January 2007 the ISBN Agency began assigning 13-digit identifiers to books and book-related products. These identifiers, "ISBN-13s", will incorporate the existing Bookland EAN into a new book identifier where the prefix can be either '978' (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.
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.
