Tsinghua University Library comprises main library, seven subject branch libraries and more than ten school or department reading rooms. In the past few years the library has expanded its collection very fast, especially in the e-resources. By the end of 2013, the total physical collections have been over 4.63 million item/volumes, the full-text e-journals in Chinese and foreign languages totals over 67,000, and the e-books increases to more than 7.99 million.

In 1996, the Library introduced the integrated library management system for cataloging and circulation management, which was the first one in China. In 2005, the library brought in MetaLib+SFX, the e-resources integration system, and established Tsinghua Academic Information Resource Portal. Now the faculty and students of Tsinghua University are able to access the library's e-resources conveniently and safely at any time and from any places.
