Because of their location at the head of the Mozambique Channel, the four islands of the Comoro Archipelago, Anjouan (or Johanna), Grande Comore (Great Comoro), Mohilla (Mohély), and Mayotte (Mayotta) have been the subject of a considerable body of literature. European ships in need of supplies for their voyages to the east, or along the eastern coast of Africa, stopped at one or all of the islands, and many travelers and ship captains published their observations on the archipelago. Literature dealing with the period before 1800 has been arranged into collections cited below, but the numerous accounts of nineteenth-century travelers ar e scattered in periodicals and books, and the major bibliographical works on the islands, by and large, cover die same ground. This essay brings together accounts of the Comoro Islands arranged in a geographical and historical, although not necessarily chronological, context; and secondary material particularly related to the events and people is also described.
