The present monograph, primarily a collection of annotated translations of these recent studies, is neither a new appraisal of Li Chih drawing on these materials nor a critical evaluation of the current Chinese scholarship on his life and thought. In a modest way it is an attempt to make these new sources of information more readily accessible to the sinological community to faciliate research. The divisions of this study are: two sections consisting of translations of new materials on Li Chih, with an analytical introduction on the significance of these discoveries, and two appendices of bibliographical accounts of primary and secondary sources down to recent times.
