If you’re moving or clearing an estate, skip this tool. Just text 702-496-4214 for free donation pickup — that’s the easier path for almost everyone. This tool is for serious collectors and researchers who already decided to sell individual high-value books and want to know which auction-house specialist to contact. NMLP doesn’t buy books at retail prices.
Reference tool for sellers & researchers
Check my books
Paste a book list — author names, titles, anything. The tool scans your list against the public NMLP reference data and tells you which entries match an indexed author or title. 67 pillar guides, 52 closed-signature-pool authors, 50 top New Mexico first editions, 89 collecting terms. Useful if you’re a serious collector deciding which titles to send to Heritage Auctions vs Swann vs PBA Galleries, or a researcher checking your list against a structured bibliography.
Not a valuation tool. A match means the title appears in my reference data — not a price prediction. NMLP is a free donation-pickup operation; I don’t buy books at retail prices. If you’re considering selling, this tool helps you know which specialty channel to ask. If you’re donating, you don’t need it — just call.

Methodology — what the tool sees and what it misses
This is a deliberately simple substring matcher running in your browser. Knowing what it does and doesn't do up front saves you from over-trusting a flag or under-trusting a non-match.
What it scans against
- 67 pillar guides — Southwest authors, regional publishers, and book-history references with full authentication methodology and pricing data. Inventory at /pillars.
- 52 closed-signature-pool authors — deceased authors whose signed inventory is fixed and tracked, with current auction comp ranges. Master table.
- 50 top New Mexico first editions — curated ranked list of the most-collectible regional first editions. Ranked list.
- 89-term collecting glossary — terminology used in book-condition grading, edition identification, and signature provenance. Glossary.
All four datasets are published as public JSON feeds at /api/ under CC-BY-4.0. The matcher pulls the feeds on page load, splits your pasted text on common delimiters (newlines, commas, semicolons, em-dashes), case-folds, and checks each token for a substring match against indexed names.
What a match means
A match means the name in your list appears somewhere in the indexed data — nothing more. Specifically, a match does not imply:
- The specific copy you have is a first edition or first printing (most matches in the wild are reprints).
- The book is signed (signature changes the value envelope by 5–100×).
- The condition is collectible (cover wear, foxing, ex-library marks all matter).
- A current dollar figure (real comps move with the market quarter to quarter).
A match is a flag to look further. The pillar guide for the matched author is the place to look — each pillar walks through edition identification, signature provenance, condition framework, and current pricing.
What a non-match means
A non-match means the name is not indexed. It does not mean the book is worthless. The reference data skews heavily toward:
- Southwest and New Mexico authors
- Closed-signature-pool authors regardless of region (deceased authors with fixed signed inventory)
- Regional New Mexico publishers (UNM Press, SAR Press, Cinco Puntos, Sunstone, etc.)
Books that are valuable but won't match include: famous-living-author firsts (most pillars are deceased authors), East Coast literary firsts outside the Top 50, textbooks and STEM monographs (route to SellBooksABQ), and trade-paperback editions of major works (rarely collectible regardless of author).
What to do based on what the tool returned
If 1–3 titles flagged
Click into each pillar guide. Verify edition (first printing? right number line? right dust jacket state?), assess condition, decide whether to keep, sell, or donate. Three flagged titles in a typical 200-book library is normal — that's the long tail of value distribution working as expected.
If 5+ titles flagged
You have a collection rather than a library. Consider booking a 30-minute appraisal call before any disposal decisions. The flagged titles plus the pillar guides will give you the framework; if multiple titles fall inside a closed signature pool, route the whole group to a single auction-house specialist rather than splitting them across consignors.
If a closed-signature-pool author flagged with multiple titles
High-attention zone. Closed pools mean the supply is finite and tracked — the auction-house specialists who handle that author already know the comp ranges and the signature variants. Don't dump the books into a generic estate sale; you'll lose 60–90% of the value to a buyer who knows what they're looking at.
If zero titles flagged but you suspect value
Text a photo of the copyright page (and dust jacket if hardcover) to 702-496-4214. Number-line identification, imprint, and dust-jacket state are the three things a photo can resolve in 30 seconds. The tool can't see those.
If you're moving or clearing an estate, regardless of result
Text 702-496-4214 for free donation pickup. Free, any condition, any quantity. The flagged titles get hand-pulled before pickup so you can keep them or route them; the rest comes with me. This is the path that almost everyone in a moving or estate situation should take — the tool exists for serious collectors and researchers, not for people just trying to get the books out of the house.
Worked examples
Estate library, North Valley
List pasted: 142 titles, mixed Southwest and general fiction.
Tool returned: 11 matches — Hillerman (4), Frank Waters (2), Edward Abbey (1), Erna Fergusson (1), N. Scott Momaday (1), John Nichols (1), Tony Hillerman essays (1).
What I did: Pulled the 11 flagged titles for inspection on pickup day. Three were signed first printings — family kept those. Two were ex-library and routed to donation. The rest cleared via my normal channels at fair market price. Total recovered for family: ~four-figure prices worth of books they would otherwise have donated unsorted.
Downsizing senior, Nob Hill
List pasted: 68 titles — largely New York Times bestsellers from 1990s–2010s.
Tool returned: 0 matches.
What that meant: Not a collection — a reading library. None of the titles fell into a Southwest or closed-pool index. Free pickup made sense. Books routed: 18 children's books to APS Title I, 12 to a Little Free Library, the rest into the resale pipeline at trade prices. The "zero matches" answer was the correct one.
Researcher building a Cormac McCarthy bibliography
List pasted: 47 McCarthy-related entries (works, criticism, secondary sources).
Tool returned: 23 matches against the McCarthy pillar.
How that helped: The pillar guide gave the researcher edition-identification details for the matches plus a pricing-tier framework. The 24 non-matches were criticism and secondary sources outside the indexed scope — no value implication, just outside what the tool indexes. The researcher didn't need a donation; she needed the structured bibliography this tool surfaces from the public JSON feeds.

How current is the reference data?
/api/ regenerate each site build (typically weekly). The Top 50 NM first editions list is reviewed quarterly. Closed-signature pools update as authors die or as new signed inventory enters the market.How it works
Every entry on this site — the pillars, the closed signature pool table, the top 50 first editions, the 89-term collecting glossary — is also published as a public JSON feed. This tool fetches those feeds in your browser, runs your pasted text against them with simple substring matching, and tells you what came back.
The point of flagging books is to keep the trophies from getting pulped. A signed first edition of a deceased author behaves differently in the used-book ecosystem than an unsigned trade hardcover of a living one. If you have something covered by a pillar guide, there's specialty knowledge attached to that title that determines where it should end up. The tool tells you what those names are so you can keep them, route them to an auction house, or include them in a donation pickup with me knowing they'll go to the right specialist instead of a recycling bin.
The tool is intentionally rough. It catches obvious matches; it misses subtle ones. A non-match doesn't mean a book has no value — it means I don't have that name indexed.
NMLP is a free donation operation. I don't buy books at retail prices — if that's what you want, an auction house is your move. No data leaves your browser. The page is statically hosted on Cloudflare; the JSON feeds are publicly cached; the matcher runs locally. View source if you want to verify.
