Encyclopaedia Islamica Online

Encyclopaedia Islamica is a projected 16-volume publication, consisting of an abridged and edited translation of the Persian Dāʾirat al-Maʿārif-i Buzurg-i Islāmī, one of the most comprehensive sources on Islam and the Muslim world. One unique feature of this work of reference lies in the attention it gives to Shiʿi Islam and its rich and diverse heritage, which makes it complementary to other encyclopedias. In addition to providing entries on important themes, subjects and personages in Islam generally, it offers the Western reader an opportunity to appreciate the various dimensions of Shiʿi Islam, the Persian contribution to Islamic civilization, and the spiritual dimensions of the Islamic tradition.

Encyclopaedia Islamica Online is automatically updated whenever a new volume has been published. New content will be added every year in alphabetical order. The project started with the letter A in 2008 and is expected to be completed in 2028.

Encyclopaedia Islamica Online is also available in print. Visit for more information.
