Robinson's volatile temperament and his impatience with administration and routine have seriously affected the survival of material. Thus little survives of his correspondence which he usually wrote in longhand and without copies, or of his public life, service on committees, advisory boards, learned societies, and in the launching of new journals. There are, however, many manuscript notes in varying lengths of sequence and a few notebooks relating to research topics. Examples are a sequence of ideas on the possible structure of strychnine, tentatively dated 1945-1947 by J.W. Cornforth, and from a later period two relatively extensive sequences of research and correspondence, on the origins of petroleum and on drug research. Lacunae in the collection are to some extent compensated for by the autobiographical material. There are the background material and corrected proofs for the first volume of his memoirs published in 1976, and substantial typescript drafts of the second volume which was unfinished at his death together with narratives, correspondence and photographs sent to him by colleagues. There are also tape-recordings of conversations with colleagues covering similar types of recollections.
