The archival materials at the Institute of History and Philology, Academia Sinica are portions of the Ch'ing Grand Secretariat Archives rescued form being recycled at a Peking paper factory. This paper intends to introduce the preservation, cataloguing, and publication of these documents since their acquisition by Fu Ssu-nien in 1929. Some of their contents will also be discussed. Despite of earlier efforts, a full-scale project for restoring and organizing these archival materials only began in 1981 and has continued to the present day. As of June 1998, approximately 154,000 documents have been registered, 98,000 have been catalogued, and 36,000 have been scanned. Those catalogued and scanned documents are available for computer retrieval (in Chinese) through the Internet by searching for any terms related to date, office or name of memorialists, and subject. This collection consists largely of routine memorials, t'i-pen, their copies, chieh-t'ieh, as well as edicts, record books, veritable-record drafts, shih-lu kao. These documents will probably be most useful to scholars interested in institutional history, Nevertheless, social and economic historians may be surprised to find how rich these materials in researching certain topics.
