Many works on Transjordan during the Mandate period are based almost exclusively upon British, American and Israeli archival material, as well as reports published by the Mandatory government, such as those sent annually to the League of Nations from 1921 to 1938. These records are important; however, they should not be used in isolation from indigenous Jordanian records. Such records do exist, are accessible, and are absolutely essential for a thorough study of the country. We herewith offer details of two relatively unknown and under-utilized bodies of Jordanian documents from the Mandate period, the records of the central office of the Jordanian Department of Lands and Survey and those of the Amman Chamber of Commerce, as examples of the types of indigenous sources which are available in Jordan today.
