A home filled with books — especially when you look at the titles — makes a statement about the readers who live there. But the things holding those books up make another statement - about your home decor taste.  JustBookends is an intriguing site which carries more than 250 types of bookends, far more than you’d find at your local bookshop. One of their best-sellers are the triangle black marble bookends, two thick triangles of dark swirled marble, perfect for holding up large or heavy books (a set is $50, and the shipping, which is on special now, is $7). Another popular choice at Just Bookends is the splashing dolphin set, bronze sculptures of dolphins leaping joyfully out of the water ($84). Another nautically themed choice is the brass ocean wave lighthouse pair of bookends; each one depicts a lighthouse with water lapping at its base. If you’re looking for a gift for a music teacher, consider a set of piano bookends($38, pictured). Made from cast resin, they’ll look nice on a shelf near the real piano. For little girls, radiantly colored butterfly bookends are a standout choice ($35); little boys might prefer the wooden train set , with the engine on one side and the train cars on the other ($35). Barnes & Noble has a classy selection of bookends, including these gleaming red heart-shaped bookends from Alabastri Duchessi Italy ($63), which could be given along with a book of love poems for a romantic gift. Alabastri Duchessi also makes fantastic green malachite alabaster eggs ($63 for the set), which would look perfect in a contemporary design setting. An amusing choice for children or adults are these playful brass polar bear bookends ($45). If you have two photos you’d like to display on your bookcase, order a set of these Pottery Barn photo bookends ($34), which come in black, espresso (brown) or white; each one holds a 3- by 4-inch photo.
