The 'Farm Hall transcripts' were made from the recorded conversations of a number of German scientists (including Heisenberg) who were interned at the end of the war in Europe at Farm Hall, a Cambridgeshire estate, where they first heard of the successful Allied atomic energy programme. The transcripts were classified until 1993 when Peierls joined others in exerting pressure to have them released, checked and published.

Contents comprise correspondence and papers about the release and publication of the transcripts; a copy of representation by a group of historians and scientists to the Lord Chancellor, and reviews of publication, etc.
