Research

Key outputs of the Institute's research on Ismaili history, its intellectual traditions and analysis of key manuscripts have led to numerous books published on Ismaili studies. In this context, two specific publication series have been developed, the Ismaili Heritage Series and the Ismaili Texts and Translations Series. We also have a series devoted to the Epistles of the Brethren of Purity, in which a complete critical edition and annotated English translation of the Rasa’il Ikhwan al-Safa’ will be published.
