The scholarly term for research concerning Somalis and Greater Somalia is known as Somali Studies. 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. Since 1980, prominent Somalist scholars from around the world have also gathered annually to hold the International Congress of Somali Studies.
