Combined with my own learning practice, this paper discusses the significance of learning bibliography.

Learning bibliography, we can see the general situation of books in a certain era, and compare the catalogues of different eras, we can see the circulation of ancient and modern books. By using the book classification catalogue and special subject catalogue, we can know the ownership of ancient books and the general situation of various documents in the same subject, so as to know fairly well. Classical catalogue writings are a key for us to understand and master the overall situation of classical literature. With the help of it, we can fully understand the historical overview of a subject and lay the foundation for further research. Therefore, in the study and research of classical literature and history, we must learn bibliography and master the bibliographic information of classical literature, the history and present situation of classical catalogue. This is an essential quality for scientific workers.
