The book is a footnote of life and memory, a sign of knowledge and intelligence, including divinity and reason, idols and destruction, praise and curse, arrogance and prejudice, truth and falsehood. The past emperors, monarchs, priests, and rulers have been controlled or slaughtered by censorship and prohibition, burning and destruction, etc. In ancient history, archaeology, war history, cultural history, and library and information science, many studies have been conducted on the burning and destruction of books, but the Western perspective is dominant, and there are nationalistic approaches and logical leaps. This study traced the truth about the destruction of the Royal Library of Alexandria in Egypt, destruction of the Baghdad libraries by the Mongol Empire, and burning more than 200,000 volumes of Korean historical documents of Japanese Government-General in Korea among the major bibliocausts with many mysteries and controversial issues in the East and West. As a result, the Royal Library of Alexandria is most likely destroyed under the rule of the Roman Empire. The massacre of the Baghdad library by the Mongolian army is a historical fact, not the manipulation and extreme exaggeration of western society. And Korean historical documents have been stolen and burned by the Government-General of Chōsen for 35 years and should be recognized as ‘200,000 + α’. Lastly, On the premise of excavating historical materials, research to investigate the truth behind the blibiocaust or libricide should be continued.
