The Encyclopaedia of Islam (also and ; EI is a common abbreviation in all three languages) is a reference work that facilitates the academic study of Islam. It is published by Brill and provides information on various aspects of Islam and the Islamic world. It is considered to be the standard reference work in the field of Islamic studies.

Reception

EI is considered to be the standard reference work in the field of Islamic studies. Each article was written by a recognized specialist on the relevant topic.

Historian Richard Eaton criticised the Encyclopaedia of Islam in the book India's Islamic Traditions, 711–1750, published in 2003. He writes that in attempting to describe and define Islam, the project subscribes to the Orientalist, monolithic notion that Islam is a "bounded, self-contained entity".

Editions

The first edition (EI1) was modeled on the Pauly-Wissowa Realencyclopädie der classischen Altertumswissenschaft. EI1 was created under the aegis of the International Union of Academies, and coordinated by Leiden University. It was published by Brill in four volumes plus supplement from 1913 to 1938 in English, German, and French editions.

An abridged version was published in 1953 as the Shorter Encyclopaedia of Islam (SEI), covering mainly law and religion. Excerpts of the SEI have been translated and published in Turkish, Arabic, and Urdu.

The second edition of Encyclopaedia of Islam (EI2) was begun in 1954 and completed in 2005 (several indexes to be published until 2007); it is published by the Dutch academic publisher Brill and is available in English and French. Since 1999, (EI2) has been available in electronic form, in both CD-ROM and web-accessible versions. Besides a great expansion in content, the second edition of EI differs from the first mainly in incorporating the work of scholars of Muslim and Middle Eastern background among its many hundreds of contributors:
