Hong Kong: Catholic Truth Society, n.d. [84p.], pocketbook format with stiff wraps in a clear plastic cover, ownership signature of a UC Berkeley professor on title page, otherwise very good. OCLC lists a second edition from 1976, but this first edition lacks date (ownership signature is dated 6/1970, however).
Divided into two sections, one listing characters by Romanized transliteration, the other arranging them by radicals.
