For the transliteration of Persian words, I have followed the Iranian Studies transliteration scheme. Diacritical marks have been excluded on all proper nouns. I have done my best to ascertain the preferred or standardized spelling of Iranian names (e.g., Khomeini, Ahmadinejad, and Khamenei). In those cases in which I could not determine a preferred spelling, I have transliterated the name according to the Iranian Studies scheme but have not included any diacritical marks.
