To facilitate teaching, learning, and research, the Library has subscribed to the online Internet version of Series of the Four Categories. Compiled during the early 20th century, this database comprises over 300 classical works and is divided into Classics, History, Philosophy, and Belles-lettres.
In addition, Four Essential Classics is also available on the same platform. This collection of Chinese classical works focuses more on practical usability, whereas Series of the Four Categories is known for its high-quality and original manuscript printing versions.
These online Internet versions allow for easier navigation such as searching within text. Both resources are accessible via the links on the Library website. No separate client program is required.
