Encyclopedia of Ukrainian Diaspora (EUD) was launched in 1987 originally as a 7-volume global project intended to cover Ukrainians living throughout the world outside of Ukraine. Its editor-in-chief was Vasyl Markus, based in Chicago. The Shevchenko Scientific Society, USA and the US-based Foundation of Friends of the Encyclopedia of Ukraine signed an agreement with the editor of the EUD to finance the project.
The global EUD project produced only Volume 4, Australia, Asia and Africa, which was published in 1995 in Kyiv by the Shevchenko Scientific Society, USA and the National Academy of Sciences of Ukraine. Work on Volume 1, United States of America, started in 2006. The first volume of the American edition of the EUD, letters “A–K,” was published by NTSh-A in 2009. The second volume, covering letters “Л–Р,” was published in 2012. The editors of the first two volumes were Vasyl Markus and Daria Markus. In March 2012, the Board of NTSh-A appointed Orest Popovych as the Editor-in-Chief of the third volume, letters “С–Я,” which was published in 2018. The co-editor of the third volume was Alexander Lushnycky. In 2021, a fourth volume with Addenda and Errata was published.
