This is an index to the agencies and their records to the record series level only. That is, it is not an index to individual items within a record series such as files, registers etc. For example, the entry under 'Missions' refers to the records series of two agencies; however, there would be references to missions in the correspondence files of a number of agencies. Agencies in this context refers to record creating bodies. These are italicised in the index. Some cross references from functional, subject and geographical terms have been included to assist retrieval.
