图书,顾名思义,是用文字、图画或其他符号,在一定材料上记录知识、表达思想并制成卷册或缩微胶片等的著作物。图书最初同书契档案不分,后来随着人类知识领域的不断扩大,逐渐成为传播思想、传播知识和积累文化的重要手段,并形成独立的形态。古代的图书是由人工书写的,写书用的材料及装帧形式也在不断变化。公元前25世纪,古埃及人用纸草写书。 Books, as the name implies, are works of art that use words, pictures or other symbols to record knowledge, express ideas and produce volumes or microfiches on certain materials. With the original files of the book regardless of the clues, and later with the continuous expansion of human knowledge, has gradually become an important means of communication, dissemination of knowledge and accumulation of culture, and the formation of an independent form. Ancient books are written by hand, and the materials used to write the books and the format of the frames are constantly changing. In the 25th century BC, ancient Egyptians wrote paper on paper.
