When it comes to the number of books, I'm afraid there is no place comparable to Peking University except the National Library. As for those libraries that have invested a lot of money, you can brag about it. Don't take it seriously A truly excellent library is a collection of books from generation to generation. Many good books are not bought with money at all. For example, Pu Songling's manuscript of Strange Tales from a Lonely Studio is in the Liaoning Provincial Library, and there is only one in the world. No library can be richer than it. Hongwu Zheng Yun, which is collected in the library of Anhui Normal University, is also the only complete book in China.
In contrast, the libraries of national key universities have about 2 million books. If there are more than 3 million copies, it will be quite rich!
The library of Renmin University of China has a collection of 3.896 million volumes.
Tsinghua University Library has a total collection of about 3.96 million volumes (20 10).
The number of books is only one aspect. The key is to make good use of these precious resources, apply what they have learned and benefit the society. That's all that matters. Otherwise, how many books will not be wasted, can only be said to be a waste of social resources!
