Somali studies is the scholarly term for research concerning Somalis and Greater Somalia. It consists of several disciplines such as anthropology, sociology, linguistics, historiography and archaeology. The field draws from old Somali chronicles, records and oral literature, in addition to written accounts and traditions about Somalis from explorers and geographers in the Horn of Africa and the Middle East. The Somali Studies International Association is the primary organization for Somalist scholars. Bildhaan, Somali Studies, Horn of Africa and the Anglo-Somali Society Journal likewise serve as the field's main periodicals. Since 1980, prominent Somalist scholars from around the world have also gathered annually to hold the International Congress of Somali Studies.
