Reallexikon der Assyriologie

The Reallexikon der Assyriologie und Vorderasiatischen Archäologie (RlA), formerly Reallexikon der Assyriologie, is a multi-language (English, German, and French) encyclopedia on the Ancient Near East. It was founded by Bruno Meissner in 1922, reformed in 1966 by editor Ruth Opificius and publisher Wolfram von Soden. From 1972 to 2004 edited by Dietz-Otto Edzard, since 2005 by Michael P. Streck.

A team of 585 different authors of many countries have been involved in the project and a total of 14 volumes and two issues of the last volume have been published until 2017. By the end of 2017 the last issues of the 15th volume will be published, finally bringing the original project into completion.
