PURPOSE: A secondary bookshelf is provided to improve the book storage efficiency by enabling users to grasp the location of books, and to prevent the purchase of an unnecessary bookcase. CONSTITUTION: A secondary bookshelf includes a shelf unit(10), a first hanging unit(21), a second hanging unit(22), and more than one absorbing body(30). The shelf unit has the length and the thickness for storing books, and is produced with metal, plastic, or wooden plates. The first and second hanging units are closely fixed to an upper plate of the book storage space on a bookshelf, and are protruded from left and right front cross section sides of the shelf unit. The absorbing bodies are formed on the rear cross section of the shelf unit to be fixed to a rear plate of the bookshelf. |
