Bulk Generate Code 128 Barcodes
Learn how to generate thousands of high-density Code 128 barcodes in bulk to label and catalog library books, archives, and document collections.

Internal Tracking vs. ISBN
When managing a university library or cataloging thousands of corporate archives, you need to assign a unique internal barcode to every single book or document.
While every book arrives with an ISBN barcode on the back, that number only identifies the title. If your library owns 5 copies of the same book, you need 5 unique internal barcodes (e.g., LIB-001, LIB-002) to know exactly which specific copy a patron checked out.
The Spine Label Constraint
Because library labels must often fit on the narrow spine of a book, you require a highly compressed barcode. Code 128 is the global standard for library cataloging because of its exceptional data density. It can encode a long, complex internal catalog string into a barcode short enough to fit on a 1-inch sticker.
Generating an Entire Catalog
Generating these labels one by one for an entire library is impossible. Using a Bulk Barcode Generator, you can automate the entire labeling process:
- Export the list of 5,000 new catalog numbers from your Library Management System (LMS).
- Paste the rows into the bulk generator.
- Select "Code 128" as the symbology.
- Export a single PDF document perfectly formatted for standard adhesive sheet labels.
- Print using a standard office laser printer, and hand the sheets to your librarians to peel and apply.
