The Chinese Materials and Research Aids Center has rendered a valuable service to students of late Ch'ing Chinese history in publishing this typeset edition of Weng T'ung-ho's diary, based on the facsimile edition printed by the Shanghai Commercial Press in 1925. The Center has made this important source material easier to use in several ways. The text is punctuated and printed in standard type, a boon to scholars not accustomed to unpunctuated, cursive writing; interlinear marks are inserted throughout, rendering proper names readily identifiable; corresponding Western dates (years and months but not days) are given alongside the Chinese; pages are numbered consecutively throughout the five volumes. And further to enhance the usefulness of the typeset edition, an index to essential proper nouns, geographical and personal, is to form volume 6 which, unfortunately, is not available to this reviewer.
