Friends of the Library bookstoreBest Friends Bookstore
North Haven Memorial Library, 17 Elm St, North Haven, CT 06473
The Friends of the North Haven Library shelve their stock in the Elm Street lobby rather than banishing it to a basement, so it is browsable the whole time the building is open, and two carts are held back for children's titles and current adult bestsellers. Everything is marked down, and the takings pay for children's and adult programming, museum passes and whatever the town budget misses. The group is newer at running events than at running the store: it was still thanking shoppers on September 2, 2026 for what it called its first ever Book Clearance Sale, held on August 21 and 22, and reporting that 700 unsold books went to New Haven Reads. Check the calendar before a long drive, because the library switches to a shorter summer grid — the 2026 window ran June 22 to September 4, closing at 6pm Tuesday and Wednesday and at 1pm on Saturday.

Woodbridge Town Library, 10 Newton Rd, Woodbridge, CT 06525
Over in Woodbridge the Friends keep a permanent aisle on the library mezzanine, called Bookstore Alley, where gently used books and puzzles run $1 to $2 and you settle up at the circulation desk, in one of the honor cash boxes, or by scanning the QR code stuck to them. Adult volunteers and Amity High School students clean every donation before it is shelved, and anything damp, dusty, mildewed or smoky is discarded rather than priced, which keeps the aisle unusually clean for the money. What the Friends judge unique or high-value never reaches that mezzanine at all — it goes straight onto their own Amazon storefront, so the aisle has been picked before you arrive. Twice a year a full sale opens up the entire inventory, once in fall and once in spring; in 2026 the spring one took the library lawn as an Earth Day sale on Saturday, April 25, 10am to 4pm.

Wallingford Public Library, 200 N Main St, Wallingford, CT 06492
Ten miles north in Wallingford, the library's used shop hides at the back of the building under a green awning, and its opening pattern takes a minute to parse: a straight 10am-to-2pm Monday, Wednesday and Friday, a split Tuesday, an afternoon-only Thursday and a short Saturday morning. New stock arrives every week from donations, and the same volunteers run an eBay storefront under the handle wallingfordbookseller, which is worth a look before you drive since better material can be listed rather than shelved. Their donation list is more permissive than most — textbooks, audiobooks, DVDs, music CDs and jigsaw puzzles all accepted — while encyclopedias, magazines, instruction manuals, Reader's Digest Condensed Books, LPs, cassettes and VHS are not. On September 2, 2026 the shop was still advertising an August offer of buy one, get one free on young adult and children's titles, and the page notes that proceeds pay for the library's January-to-April Sunday opening.

Guilford Free Library, 67 Park St, Guilford, CT 06437
Guilford closes out the shoreline run, thirteen miles east, and its Friends have had four decades of practice: the 2026 sale is the 45th, on Friday September 25 from 9am to 6pm, Saturday September 26 from 9am to 5pm and Sunday September 27 from 11am to 3pm. Tables are laid out by topic and restocked across all three days rather than emptied on the first morning, which is the detail that makes a Sunday visit worth making. Alongside adult, teen and children's fiction and nonfiction there are puzzles, paper ephemera, CDs, DVDs and vinyl, plus a section built around the country's 250th anniversary. Sunday halves every price on the tables, the bake sale holds the lobby on Saturday until it runs out, and the organizers ask you to bring your own bag.
Hours : September 25–27, 2026Website Friends of the Library saleFriends of the Cheshire Public Library Pop-Up Sale
Cheshire Public Library, 104 Main St, Cheshire, CT 06410
Cheshire, thirteen miles up Route 10, does not save everything for one weekend a year: its Friends run short pop-up sales out of the library, and the next one takes September 11 and 12, 2026, a Friday and a Saturday, from 9:30am to 4:30pm, as Friends of Connecticut Libraries has it listed. The spread is genre-sorted — hardcover fiction, biography, science fiction, cooking, American and world history, gardening, religion and philosophy, sports and trade paperbacks — with DVDs, CDs, puzzles and large-print titles alongside, and cards are taken. Volunteers screen and box donations the whole year round, which is how a two-day lobby sale can still arrive graded. A March pop-up runs the same way, so missing a date costs weeks rather than a year.
Hours : September 11–12, 2026Website
