[Updated: 2011.1.18][with diacritics]
Among these terms, 91 are derived from the list compiled by Roger Jackson, published in a 1982 volume of the JIABS. To add to this list, write to acmuller [ a ] jj.em-net.ne.jp
According to the conventions of most academic presses, if diacritics are applied, then the word would still be italicized. Also, terms such as dharma, even if found in English language dictionaries, could be used in a technical sense, such that the application of diacritics would be appropriate.
