File of letters to Yolanda Sonnabend, chiefly from C.H. Waddington

Waddington's letters to Yolanda chiefly concern arrangements for meeting and potential work opportunities for Yolanda. Many letters are undated. There are also two other letters: one from an unnamed correspondent in Rhodesia and one from Justin Waddington, concerning Waddington's book The Man-Made Future.

One letter is restricted and cannot be produced. Researchers will need to fill out a Data Protection undertaking form to access the rest of this material.
