What problem does it solve?

ISBN data integrity is critical for library catalogs; this skill validates and normalizes ISBN inputs, converts to ISBN-13, and ensures only valid identifiers are stored.

Core Features & Use Cases

  • Validate and normalize ISBN-10/13 to ISBN-13, with correct check-digit handling.
  • Generate EAN-13 barcodes using GD (no external libraries) and Code-128 barcodes for alphanumeric data.
  • Create QR codes for member cards and book labels using a bundled PHP QR code library; look up metadata via Open Library to enrich catalog entries.
  • Print spine labels and support bulk ISBN validation for batch imports.

Quick Start

Install the PHP skill in your project and run a script that validates ISBNs, generates EAN-13 and Code-128 barcodes, creates QR codes, and fetches book metadata from Open Library.
