PURPOSE: A book cover is provided wherein an upper body and a lower body which are optically transparent and light are in close contact, thereby preventing folding or abrading of a book when inserting a book into a book cover. CONSTITUTION: A book cover comprises an upper body(101), a lower body(102), and an opening(103). The upper body has a curved face facing the pages of a book, and has light and an optically-transparent material. The lower body forms one body with the upper body. The material of the lower body has good visibility, transparency, impact resistance, and thermal resistance. An opening is formed on at least one side of the book cover for inserting and removing the book. The heights of both sides of the opening are different from each other. |
