The C. S. Lewis Correspondence Project was organized in 2022 for the purpose of making available to scholars and readers transcriptions of all extant Lewis letters. This work is being coordinated through the Marion E. Wade Center and with permission of the C.S. Lewis Company and HarperCollins publishers. Its goal is to produce an electronic database of Lewis letters similar to what Cambridge University Library has done for the letters of Charles Darwin through its Darwin Correspondence Project... It is estimated that Lewis wrote more than 10,000 letters in his lifetime. . The current count of known additional letters and letter fragments by Lewis which are not found in Collected Letters stands at 732.
