 Mathews himself had been working on a revised edition of his dictionary, but when the Japanese occupiers took over the original Shanghai headquarters of the CIM (which had moved headquarters in Shanghai in 1931, and moved to the temporary Republican capital in Chongqing in 1943), unbound copies of Mathews' revision were destroyed, along with printing blocks and the CIM's library.Nevertheless, the Harvard reprint brought Mathews' dictionary to greater prominence.Today it is known simply as "Mathews"', and has been considered a great resource for students of classical Chinese, although recent scholarship is beginning to supersede it in this role.
