The Ann Thwaite Collection of A. A. (Alan Alexander) Milne contains materials almost entirely related to the development of Thwaite’s (Faber, 1990.) Over half of the collection is correspondence between Thwaite and Milne family, friends, acquaintances, and critics, documenting an exhaustive search by Thwaite from the very beginning of her research. Notable among this correspondence are over two dozen letters from Christopher Milne, a major, albeit ambivalent, source for the project. Thwaite’s October 4, 1984 letter to Christopher documents her recognition of his reluctance, and although she won him over, later correspondence shows him to waver in his level of enthusiasm, at times sending source materials and at other times describing his home to be “extremely stoney” soil for further research. Additional correspondents include Barbara Milne, John Milne, Tony Milne, and Marjorie Murray-Rust, as well as dozens of others writing with various purpose, including research queries relating to topics regarding Milne’s life and work, legal matters relating to publication, and later, relating to reception of the biography. Drafts of letters by Thwaite are located throughout the correspondence, as are approximately fifty pages of notes taken by Thwaite during interviews. Additional research materials include photocopied Milne family correspondence, photos, wills, and birth certificates, as well as many newspaper clippings and notices of Winnie the Pooh related events.
