The Yongle Encyclopedia, compiled by imperial order of the Ming Emperor Yongle, is one of China's largest encyclopedias, consisting of 22,877 volumes with 60 volumes of indexes. Compiled by Xie Jin and Yao Guangxiao, among others, it was completed in 1407. It includes a comprehensive collection of texts dating back to the early Ming dynasty, either part by part or in their entirety. Many of these texts are already lost, making them an extremely valuable resource for passing on their contents to future generations. When compiling the Complete Library of the Four Treasuries (Siku Quanshu), Emperor Qianlong of the Qing dynasty extracted lost texts from the Yongle Encyclopedia and restored them. The original manuscript was lost, and most copies were destroyed during the Boxer Rebellion and other events. Currently, only approximately 400 volumes remain worldwide. The materials being released this time are volumes 665 and 666. The Kyoto University Rare Materials Digital Archive also has other images of Yongle Encyclopedia available.

永楽⼤典 巻665-666

Bukkoku Rekishohen is a treatise on Buddhist astronomy written by Entsu, a monk of the late Edo period. In this work, Entsu attempted to systematize a theory of astronomical calendar-making that remained consistent with the worldview found in Buddhist scriptures. He criticized the Western theories of a spherical Earth and heliocentrism, which were gaining popularity in Japan at the time, and instead argued for a flat earth and the existence of Mount Meru (Sumeru), the sacred mountain at the center of the Buddhist universe. This book served as the starting point for the "Bonreki (Buddhist Calendar) Movement," which continued into the early modern era.

Prohibited Actions When Using Electronic Resources

Mass Downloading Strictly Prohibited

• Automated operations or bulk downloads using programs
• Rapid consecutive clicks (prohibited even manually)
• Access via browser prefetch functions
• Copying, redistribution, or use beyond personal purposes

Penalty If detected as excessive access, not only the individual but access from the entire university may be blocked.

Cases of Unintentional "Excessive Access"

Cases where actions are considered "attacks" by system specifications are increasing, even without malicious intent.

Case 1. Group Division of Work

Multiple people in a lab divided download tasks manually. Since the access source (university IP) was the same, it was detected as concentrated access in a short period.

Solution: Space out your downloads and only retrieve what you need

Case 2. Continuous Abstract Viewing

Clicking through HTML abstracts and full texts one after another. Even without opening PDFs, the request frequency to the server was considered "downloading".

Solution: Use abstract databases (Web of Science, etc.) for research

Case 3. Automatic Retrieval by Tools

The "auto-import PDF" setting in reference management software was ON, causing repeated mass access in the background.

Solution: Turn OFF the settings below immediately

Case 4. Physical Accident

A book fell on the keyboard, holding down the F5 key (refresh). Hundreds of accesses were recorded in just a few minutes.

Solution: Be careful around your PC when away
