Abstract: The Period of Republic of China was a historic turning point of the book binding art from traditional to modern, which has laid a profound theoretical foundation for the later maturity of book binding art in China. There are two problems in the researches of the binding art of the Republic of China:the first is that the researches are similar and lack of new ideas; the second is that the researches are fragmentary and lack of continuity and depth. Therefore, relevant scholars should further expand the depth and the breadth of the research, change the research thinking in time, and promote the research of book binding art to a higher level.
