The Coming Lewis LettersThe Lewis Legacy-Issue 78, Autumn 1998 The C.S. Lewis Foundation for Truth in Publishing
Walter Hooper says that he is now working on Volume I of Collected (and Selected) Letters of C. S. Lewis. It will include letters from 1905 to 1931 and may be published in 1999. Volume II will include letters from about 1932 to 1945 and may be published in the year 2000. Volume III will contain those from 1946 to 1963 and may be published in 2001.
According to Hooper, all the available letters by Lewis would fill seven or eight volumes, and C. S. Lewis Pte. only wants to publish three. (He does not mention how long the volumes will be, or why he and his colleagues prefer to publish less than half of the available material.) The decisions about what to include and exclude are completely up to him.
