All the articles on, and references to, Lewis which I have
consulted are listed in the Bibliography.
As for as I am aware, there has been no previous full-length
treatment of Lewis's fiction. the most complete study of his thought known to me is Chad Walsh's C.S.Lewis; Apostle to the Skeptics (1949) , which deals, often briefly, with Lewis's fiction, though not, of course, with 'The Chronicles of Narnia' and Till We Have Faces, As indicated at several points in the thesis ,I find myself in general agreement with Chad Walsh, whose book I was not able to utilize until revising my first version.
John Wain's recent autobiography, Sprightly Running (1962),
appeared in time for me to quote its account of Lewis's views on romance (Chapter XIX of this thesis ), but too late for me to supplement my brief description of Lewis In life at Oxford (Chapter II of the thesis ). It gives a fascinating account of Lewis and his circle in wartime Oxford.
