4. Oral history
Transcripts of interviews with ambassadors
Two major collections of transcripts of interviews with former ambassadors are now available online. One of them is the work of the Association of Diplomatic Studies and Training (ADST) in Washington and is to be found here. The other is the product of the British Diplomatic Oral History Programme (BDOHP) and is located on the website of Churchill Archives Centre, Churchill College Cambridge. I have found both of these resources of great value in my own research. For those interested in the (British) Commonwealth, the Commonwealth Oral History Project is also well worth a look.
