Three Steps to a Deal

From thrift store aisle to done deal — in the time it takes to read a back cover.

Scan

Point your camera at any ISBN barcode. Or use the cover scanner to identify a book just by its cover photo — no barcode required.

Match

Instantly see who in your community is hunting that exact book, what edition they want, and the maximum they'll pay. No guessing games.

Trade

Message directly in the app. Agree on a price. Pay instantly via Venmo or PayPal deep links — no third-party checkout required.

What Trove Does

Everything the Serious Thrifter Needs

Built around how book hunters actually work — at the shelf, on the go, chasing specific editions.

ISBN & Cover Scanner

Point and shoot. Scan any barcode for instant community lookup — or photograph the cover when there's no barcode. Trove identifies the book either way.

Grail Wishlist

Add books you're hunting, set a max price, and get notified the moment someone posts one. Specify down to the exact edition, publisher, or printing year.

All Editions Browser

Powered by Open Library — browse every known edition of any book, including long out-of-print paperbacks and obscure international printings. Find that specific 1967 Ace edition you've been after.

Store Sightings Map

Community members report books they spot at local thrift stores — even if they don't buy them. Browse a live map of sightings near you and see what's out there before you drive across town.

In-App Chat & Payments

Negotiate, ask questions, close the deal — without leaving Trove. Payment links for Venmo and PayPal are built right into the conversation so collecting your money takes one tap.

Trusted Community

Follow your favorite thrifters with the BFF system. Build reputation through seller ratings. Trade confidently inside a community that actually cares about books — not just flipping.

Open Library Integration

Built for the Serious Edition Hunter

There are over 30 million books in the Open Library catalog — and within a single title, dozens of distinct printings, publishers, and formats, each with different collector value. A first printing of Dune is worth hundreds. A 1980s paperback is worth three dollars.

Trove lets you browse every known edition of any book you scan or search. Your wishlist isn't just "Dune" — it's the 1965 Chilton Books first edition hardcover, first printing. When a thrifter finds one, you hear about it.

For editions that aren't in the list, the manual ISBN lookup lets you enter any 10- or 13-digit ISBN to pull up a specific printing directly. Because sometimes you know exactly what you're looking for.
