Letellier, Robert Ignatius (2015). Operetta: A Sourcebook, Volume II. Newcastle upon Tyne, England: Cambridge Scholars Publishing. ISBN9781443885089. p. 1173. (Letellier erroneously states that Mogulesko took direction of the JigniĊ£a theater in Bucharest sometime after his tour in Romania in 1906, apparently confusing him with Isidor Goldenberg, who became the director in 1913, upon the death of the former director, Lieblich; see Bercovici, 1998, p. 102.)
