Where to Find Used Books to Resell: 55 Sourcing Channels That Actually Work (2026)

If you only know two places to find books, your local thrift store and Facebook Marketplace, you're leaving most of the market on the table. The sellers who consistently pull profit out of used books aren't lucky. They've built a sourcing system: multiple channels, different rhythms, zero dependence on a single supplier.

I've spent the last few years buying and reselling books, and I built BiblioScan specifically because sourcing volume only works if you can sort the gold from the gravel in seconds. But the app is useless if you don't have books to scan in the first place. So this article isn't about pricing. It's about where the books actually come from.

Here's the full map. 55 channels in nine categories, with the trade-offs of each one. And for every category that has a physical address, the link to the directory that tells you where to go in your city.

1. Your Personal Network: Free, Fast, Underrated

This is where almost every seller should start. No competition, no driving, often no money changing hands.

• Friends and family — The easiest first source. Most people have a bookshelf they've been meaning to clear for years.
• Neighbors — Spring cleaning and moves happen on every street, every year.
• Your own Facebook page — One post saying "I buy books" pulls leads for months.
• Community groups — Local Facebook groups, WhatsApp groups, neighborhood forums.
• Word of mouth — Tell ten people you buy books. Within a month, you'll get a call about an attic.
• Family estates — When a relative downsizes or passes, books are often the last thing anyone thinks about.

The catch with this channel: it's irregular. Great for windfalls, useless for a steady pipeline. Treat it as a bonus layer, not a strategy.

2. Online Leads: Where the Volume Lives

This is where you find whole collections, not single books. One good lead can equal three months of thrifting.

• BookSaleFinder — Aggregates public library sales across regions. Check it monthly.
• Facebook Marketplace — Search "book lot", "book collection", "moving sale". Filter for newest listings, message fast.
• Craigslist — Less crowded than Marketplace, still produces bulk listings.
• Nextdoor — Hyperlocal, great signal-to-noise ratio for neighborhood downsizing.
• EstateSales.net — Study the photos. Bookshelves in the background often hide the real opportunity.
• AuctionZip — Local auction lots, often listed with poor photos and even worse search optimization.
• HiBid — Online estate auctions. Box lots of books regularly go for under $20.
• Local auction houses — The smaller and less digital they are, the better the prices.

Tip: set up saved searches and alerts. The first person to message a Marketplace lot wins. Being second is being nowhere.

3. Public Sales and Community Events

Scheduled, predictable, and almost always underpriced. The trade-off is competition: other resellers know about them too.

• Library sales — The classic. A Friends of the Library membership often gets you in an hour early.
• Friends of the Library stores and tables — Year-round donations, not just the annual sale.
• Church sales — Cheap, low competition, often priced by the bag.
• School sales — Children's books and textbooks. Variable quality.
• Community center sales — Hyperlocal, often unadvertised outside the neighborhood.
• Synagogue and temple sales — Strong on religion, history, and reference.
• University sales — Academic titles. Watch for dumped review copies.
• Museum sales — Art, design, exhibition catalogs. Often surprisingly valuable.

If you only have time for one channel per week, this is the one. The hit rate per hour is hard to beat. The recurring library sales and Friends stores are listed in the directory, with their schedule when it's published: see the "Library book sales" section for Chicago or Portland.

4. Used Bookstores: The Channel Resellers Skip for No Good Reason

Buying books from people who already sell books. It sounds counterintuitive, and it's one of the most reliable channels there is: a used bookstore sees hundreds of books a week, can't price-check all of them, and prices for its neighborhood, not for the online market. The niche title on the $3 shelf because "it doesn't move" is often the one that sells for $40 on Amazon.

• Bargain carts and dollar shelves — Out front or in the back, the $1 to $3 books the owner wants gone. That's where the titles nobody bothered to look up are sitting.
• Neighborhood used bookstores — Priced by eye, slow turnover, specialty sections (medical, law, art, local history) sold at neighborhood prices, not web prices.
• Half Price Books and the regional chains — Higher average prices, but enormous volume and regular pricing mistakes on out-of-print editions. Check the clearance section first.
• Antiquarian and specialty shops — Older stock, collector value, and owners who know their niche but not every niche.
• The trade-in counter, in reverse — Be the regular who takes the lots the store doesn't want. A bookseller who knows you calls when a whole library comes in.
• Dumps and transfer stations — Books are diverted from landfill in some areas. Free or near-free.
• Wholesale used books — Pallet-sized purchases. Gaylord boxes for serious operators.
• Bulk lots and overstock — Liquidation channels, library decommissioning lots.

Wholesale only makes sense once you can move volume. A pallet of unsorted books with no system to triage them is just expensive storage. Bookstores, on the other hand, pay off from day one: a route of three shops a week, always the same ones, and you end up knowing their bargain carts better than they do.

They're also the backbone of the directory: used bookstores are the biggest section on every city page, from Half Price Books locations to the one-room shops nobody has reviewed. Start with New York or Austin, or jump straight to your city.

5. Thrift Stores, Charity Shops and Donation Outlets

The daily grind. Lower yield per stop, but available every day of the week.

• Thrift store chains — Goodwill, Salvation Army, and their regional equivalents. Increasingly priced by algorithm, but still profitable.
• Independent thrift stores — Less data-driven pricing. Better margins.
• Hospital gift shops — Older household donations, often forgotten.
• Rummage sales — Frequently priced by the bag. A volume play.
• Habitat ReStores — Mostly furniture, but media sections show up regularly.
• Senior center sales — Non-fiction, hobbies, vintage cookbooks.
• Animal shelter drives — Almost no reseller competition.

This is where BiblioScan earns its keep. Thrift store runs work on volume: you might look at 200 spines per visit. Scanning each barcode kills the trip. Photographing whole shelves and letting the app surface the 3 books worth pulling is the difference between making this channel viable and burning out on it.

It's also the category where the directory saves you the most time. The thrift stores with a real book section, the Goodwill outlets worth the drive, the charity shops nobody advertises: all listed city by city with the address and, where published, the hours. Try Los Angeles or Houston.

6. Cleanout and Moving Sources

This is the channel most resellers ignore, and it's often the highest-leverage one. Anyone whose job involves clearing houses sees books constantly, and almost none of them want to deal with the books.

• Estate clearance companies — Build a relationship. They'll call you before the dumpster.
• Junk removal companies — Books get tossed every week. Some operators will sell instead of dump.
• Movers — Clients downsizing before a move are a constant pipeline.
• Professional organizers — Their entire business is helping people get rid of things.
• Real estate agents — Pre-sale stagers need houses emptied. Books are the first to go.
• Storage unit buyers — Auction winners rarely want the books. Offer to take them.
• Property managers — Abandoned units, evictions, tenant turnover.
• Building superintendents — Quiet but reliable. A $20 monthly relationship can be worth thousands.

The investment here is time spent building relationships, not money. One good contact in this category beats a year of thrifting.

7. Place Your Own Book Bins

The most passive sourcing method that exists. Put a labeled bin somewhere with foot traffic, and books come to you. Permission required, obviously.

• Churches — Community-minded, often willing.
• Office parks — Employees clearing their desks.
• Gas stations — High visibility, neighborhood reach.
• Shopping centers — Highest foot traffic, hardest to get approved.

Yields vary wildly. Some bins produce nothing, others fill weekly. Test two or three locations before deciding whether it works in your area.

8. Direct Outreach: The Hidden Channel

Most resellers never do this. Which is exactly why it works. The principle is simple: certain professions accumulate specific kinds of books. Reach out directly, and you cut every middleman.

• Professors — Academic libraries, often department-specific.
• Retired academics — The biggest collections. Decades of specialization.
• Doctors — Medical references. High individual value.
• Lawyers — Office libraries when firms downsize.
• Architects — Design and architecture monographs. Often very valuable.
• Artists and designers — Art books, photography, exhibition catalogs.
• Music collectors — Books, biographies, sheet music.
• Homeschool families — Curriculum and classics, traded constantly.
• Local authors — Signed copies, regional titles.
• Retired business owners — Trade books, technical manuals.

A LinkedIn message, a flyer at a professional association, or a polite email to a university department: that's the entire playbook. Most won't reply. The ones who do can change your year.

9. Flea Markets and Yard Sales

The chaotic, unpredictable, high-margin channel. Most sellers here have no idea what they're holding.

• Flea markets — Repeat vendors, room to negotiate, lots priced for clearance.
• Yard and garage sales — Best prices anywhere, especially late in the day.
• Antique markets and vintage fairs — Older books with collector value.
• Neighborhood block sales — Multiple houses, multiple home libraries in one stop.
• Seasonal town markets — Occasional sellers, minimal market knowledge.
• House clearance sales — Entire personal libraries, priced to disappear.

Two rules: arrive early for the best selection, or arrive late for the best prices. Sellers would rather discount than reload the truck. The recurring flea markets, with their day of the week, have their own section on every city page in the directory.

The Shortcut: The Spot Directory, City by City

Everything above tells you which kinds of places to work. The next question, the one everyone asks me, is "okay, but which ones, near me?" That's why we built the "Where to buy used books" directory, right on the site.

The idea: one page per city, written by hand, not a template with the city name swapped in. Each page has:

• The best spots up top, then every spot grouped by type: used bookstores, thrift stores and charity shops, flea markets, library book sales, consignment shops, book fairs.
• A card for each address: what you'll actually find there, the website, the hours when they're published, and a notice when something changed (a closure, a canceled sale).
• A map of every spot in the city, so you can plan a route.
• Local sourcing tips, nearby cities, and the date the page was last updated.

Coverage today: more than 160 US cities and over 1,700 spots, from New York to Seattle, with at least one major city in every state. The pages get revisited regularly, and the hub also shows a single map of every spot in the country. If your city isn't there yet, there's a button to request it, and that's how we pick the next ones.

Building a Sourcing System

The sellers who actually make money from this don't pick one channel. They layer several with different rhythms.

• Daily: thrift store route, online listing alerts.
• Weekly: used bookstore route, yard sales, flea markets, library sales.
• Monthly: estate sales, auctions, community events.
• Continuous: personal network, direct outreach, placed bins.

The reason this works is that any single channel has dead weeks. A diversified pipeline doesn't.

But here's the catch: more sourcing channels means more books per week to evaluate. At some point, usually around 100 books a week, manual barcode scanning becomes the bottleneck. You're not limited by what you can find. You're limited by how fast you can decide what to keep.

That's the problem BiblioScan solves. Photograph the shelf, the box, or the cart. The app recognizes every book in the photo, pulls real market data (median resale price, number of sales over the last 12 months, suggested maximum buy price) and ranks them by profit potential. The books worth pulling rise to the top. The rest stay where they are.

What sourcing gives you is opportunity. What you do with that opportunity comes down to how fast and how accurately you can sort it.

FAQ

Where can I find cheap used books to resell?

By yield per hour: library sales and late-day yard sales first, then the bargain carts at used bookstores and the neighborhood shops that price by eye, then thrift stores for the daily run, then bulk lots on Facebook Marketplace and Craigslist for volume. The channels that pay the most over a year are the ones nobody works: estate clearance companies and direct outreach to professions that accumulate books.

How do I find used bookstores and thrift stores near me?

With BiblioScan's "Where to buy used books" directory: one page per city with the used bookstores, thrift stores, Friends of the Library sales and flea markets, their addresses, a map and the hours when they're published. More than 160 US cities are covered, with at least one in every state, and there's a button to request yours.

Can you get used books for free?

Yes, and it's often the best margin: "free" groups on Facebook, Nextdoor, Buy Nothing groups, placed book bins, transfer stations that set books aside, and above all your own network. One "I buy books" post on your page is enough to start the donations. Free is irregular, so it adds to a paid route rather than replacing it.

How many books do you have to look at to find a profitable one?

In a thrift store, expect one to three winners per 200 spines. That's why sorting is the real bottleneck: past a hundred books a week, scanning barcodes one at a time can't keep up. Photographing the whole shelf and letting BiblioScan rank the books by profit is what makes that pace sustainable.

Should I buy books wholesale or by the pallet?

Only once you're already moving volume. A pallet of unsorted books with no fast way to evaluate them is expensive storage that ties up your cash. Start with the free and per-book channels, measure your hit rate, then scale to wholesale.
