Liu Zhiji is a renowned historian in ancient China, though details of his life remain limited in publicly available sources and are difficult to describe in full. Judging from his extant works, he devoted himself over a long period to the study of historical theory and historiography. His representative work, Shitong (A Comprehensive Study of Historiography), is China's first systematic treatise on historical theory, reflecting his deep thinking on the structure of historical writing, the selection of source materials, and the cultivation of historians. The library holds two of his works, both related to Shitong, commonly classified under Eastern philosophy, which shows that his influence extends beyond historiography in the narrow sense into broader intellectual and cultural fields. The writing of Shitong is concise yet rigorously argued; it summarizes earlier traditions of historical compilation and has had a profound impact on later historical criticism. As information about his birth and death dates and nationality remains unclear, this introduction can only outline his writings and scholarly standing based on available materials and widely accepted knowledge.
