Bookends are objects used to support and hold books upright on a shelf or desk. They come in various materials, such as wood, metal, or plastic, and can be decorative or simple in design. Bookends help keep books organized and prevent them from toppling over, making it easier to access and display them. Typically placed at either end of a row of books, bookends can also serve as decorative elements in a room. Some people choose bookends that reflect their personal style or interests, such as those featuring animals, famous landmarks, or artistic designs.
