Product summary

Review the store description, core capabilities, and common use cases.

LCSH Recommendation Tool helps catalogers and librarians assign Library of Congress Subject Headings (LCSH) to bibliographic records using AI.

Powered by Google's Gemini 2.5 Flash, the extension analyzes bibliographic information — title, author, abstract, table of contents, and even images of book covers or title pages — and recommends validated LCSH headings with MARC records ready to use.

Want a standalone web app instead? Try the LCSH Cataloging Assistant at https://assistant.cataloguer.name — a full-featured Progressive Web App (PWA) that supports multiple AI providers, works offline, and requires no installation. Visit https://cataloguer.name for tutorials, setup guides, and documentation for all our cataloging tools.

HOW IT WORKS

1. Enter your free Gemini API key (get one at ai.google.dev)

2. Provide bibliographic details about the work you're cataloging
