The publication of the supplement 1 of the well known and essential reference work of “A Bibliography of Eastern Asiatic Botany” is very welcome. It is a continuation of the original work, which closed with 1936, and extends through 1958. It covers the botanical literature on eastern Asia, as indicated by the title, which comprises China, Japan, Korea, Ryukyu, Mongolia and Soviet eastern Asia, as well as the major published papers appertaining to adjacent areas. It has been prepared on essentially the same pattern as the original volume while the subject index has been treated perhaps in a more thorough manner. The volume contains over 11,000 extensively and carefully annotated entries occupying 414 pages. The work is in English but the titles, papers and author names in oriental characters are fully cited, which is an improvement as compared with the original volume. It includes now the original Chinese, Japanese and Korean titles and author names as published in oriental characters as well as translations or transliterations of them. In addition, the supplement fortunately covers the extensive Russian literature, nearly 1600 entries, on Soviet eastern Asia. All Russian titles are transliterated into Roman letters and are also translated. All these improvements make this bibliography more complete than the original volume and extend its usefulness.
