The Seminar for Arabian Studies has come a long way since 1968 when it was first convened, yet it remains the principal international academic forum for research on the Arabian Peninsula. This is clearly reflected in the ever-increasing number of researchers from all over the world who come each year to the three-day Seminar to present and discuss their latest research and fieldwork. The Seminar has covered, and continues to cover, an extensive range of diverse subjects that include anthropology, archaeology, architecture, art, epigraphy, ethnography, history, language, linguistics, literature, numismatics, theology, and more, from the earliest times to the present day or, in the fields of political and social history, to around the end of the Ottoman Empire (1922/1923). Papers presented at the Seminar have all been subjected to an intensive review process before they are accepted for publication in the Proceedings. The rigorous nature of the reviews undertaken by a range of specialists ensures that the highest academic standards are maintained. A supplementary volume, ‘Languages, scripts and their uses in ancient North Arabia’ edited by M.C.A. Macdonald (ISBN 9781784918996, Archaeopress, 2018), is also available containing the proceedings from the special session held during the seminar on 5 August 2017.
