=== In Indian and Chinese Civilizations ===
In ancient Sanskrit literature, works such as the ''Sushruta Samhita'' and the ''Charaka Samhita'' (1st century BCE) were systematically divided into books and chapters, which were often listed at the beginning.
In China, during the Han to Tang dynasties (206 BCE – 907 CE), classification catalogues began to appear in official records. One example is the ''Hanshu'' (Book of Han), which organized works by topic and included early content tables.<ref>Harwit, ''Knowledge Systems in Ancient India'', Journal of Historical Epistemology, 1997.</ref><ref>Joseph Needham, ''Science and Civilization in China'', Vol. III.</ref>
