In September 1991, the West Library (Yifu Library), designed by an academician of Tsinghua University, Guan Zhaoye, was built. The construction was supported with a donation by Sir Run Run Shaw and an appropriation by the Ministry of Education. The West Library followed the same architectural style and was integrated harmoniously into the Old Library.
Since 1999, the university has successively established a number of subject libraries: Humanities & Social Sciences Library, Economics & Management Library, Law Library, Architecture Library, Arts Library, and Finance Library. These subject libraries use an integrated library management system to provide services to readers across a unified platform.
During the Centennial Anniversary of Tsinghua University in 2011, the new Humanities & Social Sciences Library, located in the core teaching district of Tsinghua University, was completed. It was collaboratively designed by the famous Swiss architect, Mario Botta, and the China Academy of Architectural Sciences. It has become an important place for hosting academic and cultural resources and exchanges for the university.
