Bibliographical categories in the Chi-Know-Po library are modeled after theSuishu: Jingjizhi隋書經籍志 (Treatise on Classics and Collected Writings of the Book of Sui).Shi史 correspond to the realm of historical writings (official history as well as other kinds of historical writings), along with writings on propriety, punishments and law, geography and the like. It partly overlaps with theShu Shu術數 (Techniques and Numbers) in theHanshu: Yiwenzhi藝文志 (Treatise on Classics and Texts of the Book of Han). At this stage, the project does not include texts that belong to this bibliographical category.
