Good books go missing all the time. They sit in boxes after estate sales, pile up at library fundraisers, and get pulped when a publisher prints too many. We find them, check them, and match each one to a reader who will actually love it.
Every pre-loved book has already been chosen once. We just help it get chosen again.
Book boxes usually mean brand-new releases at full price. That works if you read one book a month and like what everyone else is reading. Most readers we know are messier than that. They want variety, they read in bursts, and their shelves are already full of books they bought new and read once.
So we built the Society around pre-loved books. It keeps the price fair (three books for $25, shipping included), it keeps books out of the pulper, and it means your box can hold a 1970s cult novel next to last year’s book-club favourite.
The surprise is the fun part, but random gets old. Your box is matched to the Sniff Test you take when you join, sharpened by every rating you give, and checked by a person before it ships.
We buy from places where books would otherwise sit unsold or be thrown out, and we pay fairly when there’s someone to pay.
Library friends groups sell donated and withdrawn books to raise money for their branch. We buy in bulk, usually on the last day when what’s left would otherwise be recycled. The money goes back into the library.
Supports local librariesWhen a reader’s library is sold, the shelves often go as one lot. We sort every book and keep the collection travelling instead of sending it to a dumpster.
A lifetime of reading, rehomedPublishers and booksellers return and clear unsold stock. Some of it is perfectly good and heading for the pulper. These copies become our Like New strays and some of our Fresh Ink picks.
Saved from pulpingMembers send us books they’re done with and get credit toward their next box. A book you loved can become someone else’s Match next month.
How trade-ins workNeighbours, schools and clubs give us boxes of books. Anything we can’t ship goes on to one of the partners listed further down this page.
Nothing wasted on purposeBefore a book can go in a box, a person opens it, flips every page, sniffs it (really), wipes it down and gives it an honest grade.
Looks unread. Maybe it was. Tight spine, crisp pages.
Gently read. Spine intact, pages clean, maybe a little shelf wear on the cover. Our default standard.
Visibly loved: a creased spine or a name inside the cover, but no damage. Only sent to members who opt in to well-loved copies.
Any smell of smoke, must or mildew. Loose or missing pages, water damage, heavy highlighting or notes. These go to the next section.
Not every book makes the cut. We work down this list in order and only recycle what nobody can use.
Volunteer groups that mail books to incarcerated readers often need dictionaries, paperbacks and non-fiction. Each program has its own rules (usually paperback only), so we sort to their lists.
Children’s books and easy readers go to local literacy nonprofits, classrooms and family shelters.
Good-but-not-boxable books go into the neighbourhood book-exchange boxes run by volunteer stewards near us.
Books that are mouldy, smoke-damaged or falling apart can’t be passed on safely. We strip the covers where needed and send the paper for recycling.
We’d rather under-promise. Here is exactly what our impact numbers mean and what they leave out.
A book counts as rehomed when it ships to a member in a box. We count each physical copy once per trip, so a book that travels to three readers through trade-ins counts three times, because it did three jobs a new book would otherwise have done.
Two widely cited studies put one new book at about 2.7 kg (Wells et al., 2012) and 4 kg (Book Industry Study Group, 2008) of CO₂-equivalent. Greener print runs come in lower, so we use a deliberately low 1 kg CO₂e per book rehomed.
This assumes each stray replaces a new book a member would otherwise have bought. That won’t always be true, which is another reason we use the low figure.
That means our figure is an estimate of new-book production avoided, not a measure of our total footprint. We don’t claim to be carbon neutral, and we don’t buy offsets to say so.
We estimate 300 g of paper per book, a typical weight for a trade paperback.
We publish live totals on the home page once we’ve rehomed enough books for the numbers to mean something. If better research changes the estimate, we’ll update this page and say what changed.
Dewey’s head is a book and his ear is a dog-eared page. He grew up behind the Dewey Decimal shelves, which is where the name comes from.
He runs the Sniff Test, guards the wildness dial and gets visibly excited when you rate a book five wags. He does not chew the stock.
Stray Book Society started in 2026 with a garage full of library-sale boxes and a stubborn belief that good books deserve more than one reader. We sort, grade, match and wrap every book ourselves, and we answer every email with a real person.
If you run a library sale, an estate sale business, a school book drive or a Little Free Library and want to work with us, we’d love to hear from you.
