Although this is the second-oldest Tibetan-to-English dictionary, it still retains value. Each word is given in Tibetan script and in a transliteration system. Although Das' dictionary ransacked this dictionary for entries, it did not take everything. Thus, this remains an excellent complement to the Das dictionary.
"If you want to learn classical Tibetan, you can do no better than to sit down and read A Tibetan-English Dictionary by H. A. Jaschke.... I do not think that any other scholar of Tibetan has ever equaled the linguistic insight exhibited in this dictionary."--Stephan V. Beyer, The Classical Tibetan Language
