KSU DChi15 hasn't been online in over a year, but I just found these pdfs of old Manuals and Cornerstones online, and I was so surprised/thrilled. Yes I do plan on spending the rest of my night reading these!

ETA: I love that the chapter title "The Essence of Good Taste" has remained in the Cornerstone since at least 1939
