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. Most of the papers published in this volume were presented at a Special Session of the fifty-first Seminar for Arabian Studies, held at the British Museum on 5 August 2017. Its subject was 'Languages, scripts, and their uses in ancient North Arabia' and it was held to celebrate the completion in the previous March of Phase 2 of the 'Online Corpus of the Inscriptions of Ancient North Arabia' (OCIANA).
