There is actually one step prior to doing more of Warren Lewis's diaries--The Letters of J. R. R. Tolkien. This update is based on additional information that has come from reading the first half of The Letters of J. R. R. Tolkien. Occasionally, I was able to remove the word “presumably” from a date that the Inklings met, added some data from meetings between Jack and Tollers, an occasional reference to an Inklings meeting not otherwise noted, footnoted some references more accurately (instead of using William Griffin’s Clive Staples Lewis, which was drawing on Tolkien’s letters), and, though I had previously worked through the index of Tolkien’s letters and its references to Jack, added some additional information because of a closer reading. A lot of the additional information (about a thousand words) has to do with the progress Tolkien made on writing The Lord of the Rings, which I include only because Jack was such an influence on that book and heard the book read chapter by chapter at Inklings meetings.
This is the latest Lewis chronology:
The file that appears below lists all works of C. S. Lewis in chronological order (now 488 in number, one more than the previous version because of the addition of the brief "Undergraduate Criticism" from 1960) in the location where they were first published or delivered (if spoken) as far as I am able to determine. Corrections are welcome. This version, slightly revised and added on March 18, 2017, includes works listed in the bibliography of Adam Barkman's C. S. Lewis & Philosophy as a Way of Life. It also includes the recently discovered (by Christopher Marsh) "A Christmas Sermon for Pagans."
This file describes what is happening in Oxford, Cambridge, the UK, and Europe at the time that Lewis writes his various poems, essays, and books, dividing the life and writings of Lewis by academic topic, i.e. English, Philosophy, History, etc.
