Ironically I ended up with many, if not all, of Corson's checklists so think I know some of what his inventory probably was, depending on if he was counting his collection as inventory. Shown before, but for our newer members, here is one index card from him and a page of a letter from Jefferson to him. I have his "Bray Book of Checklists, 1950" as well as stacks of other papers and lists....Eventually much of it will be shown on the board.
