Barcodes are used in libraries to label books, magazines, CD/DVDs, and even patron cards. Most libraries in South Dakota use codabar barcodes. Codabar barcodes are the most frequently used barcodes in libraries.
The two main types of barcodes used in libraries are Code 39 and Codabar.
Code 39 was the first alphanumeric symbology to be developed. The rectangle of lines and spaces translates into 10 digits, but they are not displayed. The first digit is used to identify whether the barcode is for a patron or an item. The next two digits identify the institution. The last seven digits are a unique code which represent either a patron or an item.
Codabar barcodes are the most frequently used barcodes in libraries. The rectangle of lines and spaces translates into 14 digits. The first digit is used to identify whether the barcode is for a patron or an item. The next four digits identify the institution. The following eight digits represent patron or item information, and the final digit is an error-checking digit. See example below:
Contact SD State Library
Most libraries in South Dakota use codabar barcodes. To ensure consistency across the state it is recommended that libraries continue use of codabar barcodes. It is also recommended that before ordering barcodes, libraries contact the South Dakota State Library. The staff at the State Library can assign your library a barcode number. Contacting the State Library will guarantee that your library's barcode number will not duplicate another library's barcode number.
