Xuanlantang congshu 玄覽堂叢書

Xuanlantang congshu 玄覽堂叢書 "Collectanea from the Hall of Mysterious Contemplation" is a series of collectanea (congshu 叢書) compiled by the scholar Zheng Zhenduo 鄭振鐸 (1898-1958). It includes 31 books, mostly rare historiographical texts from the Ming period 明 (1368-1644) that were prohibited for circulation during the Qing period 清 (1644-1911).

The series was published in 1941 as a private print in Shanghai. There are two sequels, the Xuanlantang congshu xuji 玄覽堂叢書續集, including 24 books and published in 1947, and the Xuanlantang congshu sanji 玄覽堂叢書三集 with 12 books, published in 1948. The two post-war collections were published by the National Library 國立中央圖書館. All three series reproduce old original prints, which makes them all the more valuable not only for historians but also for scholars studying the history of publication.
