There are many libraries in Harvard, the most famous of which is Vidal Library, which is the main library (comprehensive library) with the largest collection of books in Harvard. It was built by the parents of a Harvard student who died in the Titanic incident to commemorate his son's donation. Vidal is the student's name. There is a special condition when donating money to build this library, that is, all students who use this library must be able to swim, probably because if Vidal could swim, he could have avoided this disaster. This library is not open to the public. You must have a Harvard certificate to enter. The graduation ceremony of Harvard University is usually held in front of this library.

For China people, the Harvard Yanjing Library is also very famous. It is a specialized library for East Asian studies at Harvard University, with the largest number of books on East Asia in American universities, including English, Chinese, Japanese, Korean and Mongolian, as well as rare books of the Song Dynasty and inscriptions by many celebrities. There is a pair of stone lions at the door, which highlights the characteristics of East Asia.
