The "Rasa’il Ikhwan al-Safa’" are available in print through a variety of Arabic editions, starting from the version established in Calcutta in 1812, then followed by the edition of Bombay of 1887–1889), then by the edition of Khayr al-Din al-Zirikli in 1928 in Cairo, and the Beirut Sadir edition by Butrus Bustani in 1957 and the version set by ‘Arif Tamir in Beirut in 1995. All these editions are not critical and we do not yet have a complete English translation of the whole "Rasa’il" encyclopedia.
