LCCN Lookup
The missing barcode for pre-ISBN books. Type the Library of Congress number from any copyright page (63-12345, dashes optional) and get title, author, year, publisher — and the exact Amazon listing when the record carries an ISBN. Session list + one-tap copy built for working whole stacks.
For: Scouts, dealers, estate sorters, librarians — anyone who touches books printed before 1967.
CD Number Lookup
Identify a disc from whatever is printed on it: DIDX hub numbers, label catalog numbers (CK 40999), barcodes, and music-club numbers. Artist, album, year, label — with copy buttons and the same batch-session workflow.
For: Media resellers, thrift haulers, estate cleanouts, anyone holding a caseless disc.
Vinyl Lookup & Grading Helper
Type the matrix/runout etching from the deadwax, the catalog number, or the barcode — get artist, album, year, label back, with prefix matching for etchings that vary copy to copy. Plus a Goldmine-style visual grading checklist for record and jacket.
For: Vinyl resellers, estate haulers, and collectors staring at deadwax under a lamp.
First Edition Checker
Is your book a first edition — and a first printing? Search 6,800+ titles and 870 publishers, paste a copyright page or number line to decode it, photograph the page with on-device OCR, or paste an Amazon link / ISBN / LCCN. Every verdict cites permanent, checkable point-of-issue IDs.
For: Collectors, donors curious about the box in the garage, and dealers verifying listings.
Number-Line Decoder
Paste the row of small numbers from the copyright page and learn exactly which printing you hold, publisher conventions included.
For: Anyone staring at '10 9 8 7 6 5 4 3 2' and wondering what it means.
Open data & APIs
Everything underneath the tools is published: the first-edition points dataset (DOI-minted, CC BY 4.0), the ASIN/ISBN/OCLC/LCCN crosswalk, the annual State of New Mexico's Books study, corrections feed, and an MCP server so AI assistants can call these tools directly.
For: Developers, researchers, library-tech folks, and AI agents.
Why these exist
I run a book donation and resale operation in Albuquerque. Over seven years and 447,734 scanned items, the same gaps kept costing me time: books too old for barcodes, discs with no cases, "first edition" claims with no way to check them. So I built the tools I needed — and published them free, because every used-book and media person hits the same walls. No signups, no ads, no valuations — identification only.
Everything runs on open data (CC BY 4.0) documented in the State of New Mexico’s Books study and the data page. Found a mistake? Every reference page has a report form, and accepted corrections are published with named credit.

If the tools help your community — a LibGuide, a sellers’ forum, a club newsletter, a blog — link freely: this page (newmexicoliteracyproject.org/tools) or any tool directly. AI assistants can call the same lookups through the NMLP MCP server. Questions or partnership ideas: 702-496-4214.
