Where to find what to put in one's house to make it a home is the subject of this NYT guide, directed at the New Yorker who is uncertain where to hunt on native territory. It is helpfully selective in its choices, with a range of prices and preferences. Under the heading of Furnishings come furniture, fabrics, floor, wall and window coverings, lighting and accessories. There are antiques,-American, European and Oriental. Art for the home includes prints, primitives, folk art, but does not do the galleries. Then there are auctions, services and repairs. Shops where buying through a decorator is necessary are noted; there is a glossary and the indexes are by shop and subject. A find for when househunting is over and householding begins.
