Book Shelf

A bookcase, or bookshelf, is a piece of furniture, almost always with horizontal shelves, used to store books. It may be fitted with glass doors. A bookcase consists of a unit including two or more shelves which may not all be used to contain books or other printed materials. Shelves may be fixed or adjustable to different positions in the case.
A shelf is a flat horizontal plane which is used in a home, business, store, or elsewhere to hold items of value that are being displayed, stored, or offered for sale.
