Overview
Bookland barcodes are EAN/JAN-13 barcodes that use a specific format exclusive to books. Generating a bookland barcode is the same as generating an EAN/JAN-13 barcode using the 978 numbering system.
Encoding
Bookland barcodes can encode 10 digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. You can use an additional pipe("|") to encode supplemental data. Refer to remarks below for additional information.
Structure
Bookland has the following structure:
- Start guard bars (always bar+space+bar).
- Left half - 7 digits encoded using the encoding schema A or B.
- Center guard bars (space+bar+space+bar+space).
- Right half - 6 digits encoded using the encoding schema C.
- Stop guard bars (always with a pattern bar+space+bar).
The barcode structure expresses four main components, the number system, manufacturer code, product code and checkdigit.
Number system: In the human readable text, the number system appears to the left of the start guard bar and continues into the first one or two digits after the guard bar. The number system for Bookland is always 978. If you specify the Bookland barcode type, Toolkit automatically applies the 978 number system.
Manufacturer code: In the human readable text, the manufacturer code appears between the start and center guard bars. The numbering authority assigns the manufacturer code.
Product code: In the human readable text, the product code appears between the center and stop guard bars. Each manufacturer assigns the product code, which provides 99,999 different combinations.
Checkdigit: In the human readable text, the checkdigit appears to the right of the stop guard bar. Toolkit automatically calculates and appends the checkdigit to your 12 digit encoding.
Requirements
Bookland barcodes always use the 978 number system and the remainder of the barcode consists of specific parts from the book's ISBN number.
An ISBN is a 10-digit number preceded by the letters ISBN. Typically, an ISBN uses an OCR-A font. The number consists of four parts with variable length, separated by hyphens or spaces. The parts in order are the Group Identifier, Publisher Identifier, Title Identifier and checkdigit. Toolkit does not generate ISBN numbers. Regional agencies in every country assign ISBNs.
The Bookland barcode value consists of the 978 number system and the entire ISBN, minus the checkdigit plus a checkdigit generated by Toolkit. For example, if the ISBN of a book were "968-26- 1240-3". The complete Bookland code generated by Toolkit would be "9789682612404".
Remarks
The Bookland barcode format allows for additional supplemental data, which you append to the end of the encode value using a pipe character ("|"). For example, if you specify "71245126" as your 12-digit value and "95000" for your 5-digit supplemental value, you would change the value to "71245126|95000"
Additionally, you will need to pay attention to the following values when generating 5-digit supplemental barcodes:
- 90000 — The value indicates a book has no suggested retail value.
- 99991 — The value indicates the book is a complimentary copy.
- 90001 to 98999 — Publishers use these values for internal purposes.
- 99990 — The value indicates the book is "Used" as dictated by the National Association of College Stores.
