The table of contents of the book will help us understand what the book is about, and most of it will also reflect the framework structure and theme ideas, which will guide us in the direction of the following reading. Every book worth opening contains more or less treasures and the essence of the author's thoughts, so looking at the table of contents, whether it has a framework or not, and whether the content is long or short, is not a time-consuming task.
One of the characteristics of modern bibliographies is the emergence of catalogs that reflect new learning and play an introductory role, such as "Bibliographic Questions and Answers" compiled by Zhang Zhidong in 1874 and Liang Qichao's 1896 4 volumes of "Bibliography of Western Studies".
In the latter bibliography, add "circle knowledge" at the top and "knowledge language" at the bottom. The appendix "Reading Western Calligraphy" points out the quality, depth and reading method of the book. Bibliographies that introduce the new study of Western learning include: Wang Tao's "Taiwan Bibliography", Kang Youwei's "Japanese Bibliography", Xu Weize's "East-Western Studies Bibliography", Shen Zhaoyi's "New Study Bibliography Summary", etc.
