Oxford Dictionary of Byzantium

The Oxford Dictionary of Byzantium (ODB) is a three-volume historical dictionary published by the English Oxford University Press. With more than 5,000 entries, it contains comprehensive information in English on topics relating to the Byzantine Empire. It was edited by Alexander Kazhdan, and was first published in 1991. Kazhdan was a professor at Princeton University who became a Senior Research Associate at Dumbarton Oaks, Washington, DC, before his death. He contributed to many of the articles in the Dictionary and always signed his initials A.K. at the end of the article to indicate his contribution.
