As with being too thin or too rich, you can never have too many bookshelves. Unfortunately, they're damned expensive. If you'd rather not spend multiple hundreds for the chichi rustic style of Pottery Barn or risk loading a decrepit antique with heavy volumes, stop by Books & Bookshelves, a modest corner shop with a surprisingly complete collection of unfinished shelves (plus tables, chairs, and other furniture). For about $150, you can get a simple six-shelfer that you can paint or finish yourself in a matter of days -- or leave it unfinished, for that live-work loft look of yesteryear.
