What is Code 128 for Library Books?
Libraries run circulation on barcode scanners: every book, DVD and laptop carries an accession barcode, and every borrower card holds a patron barcode. Most integrated library systems (ILS) read Code 128 for these labels - it encodes the letters-and-numbers accession schemes libraries use and prints cleanly on small spine and property labels. This generator batches a whole accession run or a shelf of relabelled stock in one pass.
Common Uses for Code 128 for Library Books
- Accession number barcodes for new book stock
- Member and staff card barcodes for circulation desks
- Shelf and collection location labels for reorganisation
- Equipment, laptop and key tracking within the library

Frequently Asked Questions
Do libraries use Code 128 or Codabar?
Historic libraries used Codabar, but modern ILS installations and relabelled collections use Code 128 - it is denser, encodes letters, and every current circulation scanner reads it. Match whatever your ILS vendor specifies.
What format should library accession numbers be?
Whatever your ILS issues - commonly a fixed-length numeric or a prefix plus number, like LIB-2026-00417. Code 128 encodes both styles; keep lengths consistent so labels line up on spines.
What size should book barcodes print?
Standard book labels are roughly 30x12mm with the barcode around 25mm wide. Keep the quiet zone clear of spine art, and laminate or cover with archival foil for durability.
Can I print barcodes for a whole accession batch?
Yes - paste the accession list, one per line, and print label sheets for the full batch. Generate the accession numbers first with the serial number generator.
