  The historiography of the Crusades is concerned with their "history of the histories" during the Crusader period. The subject is a complex one, with overviews provided in Select Bibliography of the Crusades, Modern Historiography, and Crusades (Bibliography and Sources). The histories describing the Crusades are broadly of three types: (1) The primary sources of the Crusades, which include works written in the medieval period, generally by participants in the Crusade or written contemporaneously with the event, letters and documents in archives, and archaeological studies; (2) secondary sources, beginning with early consolidated works in the 16th century and continuing to modern times; and (3) tertiary sources, primarily encyclopedias, bibliographies and genealogies.
