A bookshelf is a piece of furniture that holds books and sometimes other things like decorative objects or figurines.
You see bookshelves pretty much everywhere – in homes, offices, libraries, and even some classrooms. They usually have multiple shelves, which can be adjusted to hold books of different sizes. People often put their favorite books on the top shelf so they're not buried under everything else. You might also find a few framed pictures or vases on a bookshelf if it's in a cozy living room or study area. Sometimes, especially in old houses, bookshelves are built into walls or have beautiful carvings – they can be really special and ornate.
(furniture) A shelf or shelves for storing books for easy visual reference.
