A bookcase may be fitted with glass doors[1] that can be closed to protect the books from dust or moisture. Bookcase doors are almost always glazed with glass, so as to allow the spines of the books to be read. Especially valuable rare books may be kept in locked cases with wooden or glazed doors. A small bookshelf may also stand on some other piece of furniture such as a desk or chest. Larger books are more likely to be kept in horizontal piles and very large books flat on wide shelves or on coffee tables.
In Latin and Greek the idea of bookcase is represented by Bibliotheca and Bibliothēkē (Greek: βιβλιοθήκη), derivatives of which mean library in many modern languages. A bookcase is also known as a bookshelf, a bookstand, a cupboard and a bookrack.[2] In a library, large bookshelves are called “stacks.”
A cabinet is a case or cupboard with shelves and/or drawers for storing or displaying items. Some cabinets are stand alone while others are built in to a wall or are attached to it like a medicine cabinet. Cabinets are typically made of wood (solid or with veneers or artificial surfaces), coated steel (common for medicine cabinets), or synthetic materials. Commercial grade cabinets usually have a melamine-particleboard substrate and are covered in a high pressure decorative laminate, commonly referred to as Wilsonart or Formica.
Cabinets sometimes have one or more doors on the front, which are mounted with door 
hardware, and occasionally a lock. Cabinets may have one or more doors, drawers, and/or shelves. Short cabinets often have a finished surface on top that can be used for display, or as a working surface, such as the countertops found in kitchens.
A cabinet intended to be used in a bedroom and with several drawers typically placed one above another in one or more columns intended for clothing and small articles is called a dresser or a chest of drawers. A small bedside cabinet is more frequently called a nightstand or night table. A tall cabinet intended for clothing storage including hanging of clothes is called a wardrobe or an armoire, or (in some countries) a closet if built-in.
