The World Language Center is a section of the Yale Bookstore, with its own devoted and multi-lingual staff ready and able to help you with anything you need. The center offers an extensive selection of books with audio components for learning languages, carrying almost everything published. The rest of the store is literature in foreign languages. The European languages are the best represented, with full selections of things like the French folio series. But there are also sections devoted to more obscure languages, such as the Scandinavian languages, and non-European languages. This is a totally unique thing to have in an otherwise fairly generic Barnes and Noble.
TYCO is a full service copy shop which also offers copy machines for DIY copying (with a counter). Their price per page is quite reasonable, so it's a good place to make flyers or make copies for anything you need a lot of. They also do other printing and copying services, particularly things like making business cards, and they make it easy to do. They're also one of the major sources for course packets, although they're a little pricier than York in that department. They're not open 24 hours, but do keep good hours and are right on the Broadway shopping area.
The Book Rack is one of the very few used book stores in the entire Cape area, so it fills a need that otherwise goes unsupported. One major attraction is that you can trade books back in for store credit, which makes it the perfect place to pick up ephemeral paperbacks that you want to read but don't want to keep or pay full price for. As a result, they have an especially large selection of romance novels and other types of genre fiction, but not as much in the area of serious reading. Good for looking for popular materials.
This is a store selling only material made by Danskin, so you can try things on instead of just buying from a catalog or another retailer. Half the store is clothing for dancing, particularly for young women. They have an excellent and adorable selection of ballerina clothes and tiaras, as well as things for professional dancers. The other half of the store is for women's clothing, things specifically for dancing or yoga or more general exercise gear. Staff is very helpful and the clothing is divine.
The Book House is a used bookstore which occupies almost all of an old house. The entire place smells like books, and is wonderfully crowded. It's not the easiest place to find specific items in, but this is the kind of book store you go to in order to look at books, not to find a perfect copy of something quickly. The staff are friendly and helpful, and offer good prices for used books. I've had a lot of luck here in their science-fiction and fantasy section, where they have plenty of both paperbacks and hardcovers.
Not far from Powell's is O'Gara and Wilson, specializing in used and antiquarian books. They always have a fantastically interesting front display. You're likely to find higher prices here than elsewhere, but also far more unusual and valuable books. They do carry normal used books as well, but the essence of the store is the old and rare.
57th Street Books is part of the network of the Seminary Co-Op, so the same discount for shareholders works at both stores. This subterranean store is the popular/general interest side of the Seminary, carrying children's books, sci-fi, mysteries, biographies, all kinds of genres. They have frequent book readings/signings and events for children. Great place to browse and find something new to read.
Hello Boutique is yet another in the string of expensive clothing stores which line Chapel Street in downtown New Haven. It has a great location, next to Atticus and Scoozi, but always seems to be fairly empty. The target audience is middle-aged and older women, and a lot of the clothing is just bizzare, and priced well up-scale. The mannikins in the window are always worth a look to wonder if anyone would actually ever wear what was on display there.
Jet Cleaners is a little out of the way from campus, but worth the extra walk. They have unusually late open hours, even on Sundays, so you can pick up things and drop them off when you're able to. Their surface is fast and dependable, prices are good, and they cleaned an item of mine that I feared was unfixable. In addition, they use nicer hangers for clothes than some other cleaners I've used in the past. Recommended to me by a number of people who really care for their clothes.
Buchheit's is a farm store the size of a Wal-Mart, and has a correspondingly huge selection of materials. You can buy everything from clothing to medicine to lumber to live chickens here, and get the support of a staff who know what this stuff is to be used for. It's a good alternative to the chain DIY stores for many items. For city dwellers, particularly attractive is their birdseed in bulk, at very good prices, and a great selection of sturdy bird feeders. They also sell a very wide variety of mulch and other materials for gardens, and are helpful in loading up your vehicle to take it all home.
