Bibliotheca Zi-Ka-Wei, Research library in Xujiahui, Shanghai, China

Bibliotheca Zi-Ka-Wei is a two-story library in Xujiahui whose present building, planned in 1897 and completed in 1906, has twelve rooms. Its first floor, for Chinese books, imitates the Wenlan Pavilion of the Qing imperial Siku Quanshu library; the second floor, for Western-language books, follows the style of the Vatican Library.

A French Jesuit missionary founded this library in 1847 as a small collection within a seminary setting, which eventually developed into a separate building. The facility has operated as a branch of the Shanghai Library system since 1956.

Locals called the large building among the old ginkgo trees "The Great Library." The first floor held Chinese books in a room modelled on the Wenlan Pavilion, which housed the Qing Siku Quanshu, while the second floor held Western-language books in a style imitating the Vatican Library. Ownership stamps in the books record names such as Zi-ka-wei Reservata Bibliotheca and Bibliothèque de Mission.

The library sits in Xujiahui, reachable via Xujiahui station on Metro lines 1, 9 and 11. It was closed to the public for decades and only reopened to all visitors after renovation in 2002. The Chinese collection occupies the ground floor, the Western-language collection the upper floor.

The library's European collection spans more than ten languages, including Hebrew, Latin and Greek, alongside major world dictionaries and encyclopedias. At its height it held over 100,000 titles in 200,000 volumes, and after the Oriental Library burned in 1932 it was the largest library in Shanghai.
