In order to preserve the materials of the National Central Library (NCL) and shed light on traditional academic culture, from the outset of its creation the NCL has placed high priority on collecting rare books. By forming a network of likeminded scholars in Shanghai and Hong Kong during the War, the scale and significance of its acquisitions reached an outstanding level. With cooperation between the government and the people, in the end many rare works were saved from being exported to a foreign country. Being one of the most remarkable achievements in collecting precious works of the 19th century, much scholarship has been written on this feat. However, as most focus on the so-called "Comrades for the Preservation of Literature" in Shanghai, they tend to overlook the role that Hong Kong played in gathering and transferring the works to Shanghai, especially the Fung Ping Shan Library's provisional storing of the works. While also referring to such previous works, this article was based on the archives of the National Central Library when it was situated in the mainland. It would be appreciated if local historians would con-tact the author to submit their comments and insights.
