The present text is a translation of the Lintai gushi by Cheng Ju, a book that deals with the imperial book collections under the Northern Song. The library collections of the early Northern Song were created from scratch, only to be partially destroyed again in the disastrous fire of 1015 and during the shift of the capital from Kaifeng to Hangzhou. Cheng Ju’s Lintai gushi is the oldest surviving source of information on the Northern Song (960-1126) imperial libraries. The Lintai gushi bears witness to the various activities undertaken to rebuild comprehensive book collections and thus to fill the gap in the history of imperial Song libraries.
