In English-language literature, the name of Yaqub Beg has also been spelt as Yakub Beg (Encyclopædia Britannica), Yakoob Beg (Boulger, 1878) or Ya`qūb Beg (Kim Hodong, 2004). Authors using Russian sources have also used the spelling Yakub-bek (Paine, 1996).[4] A few publications in English written by Chinese authors spell his name Agubo, which is the Pinyin transcription of the Chinese transcription of his name, 阿古柏 (Chinese: 阿古柏帕夏; pinyin: Āgǔbó pàxià).
