TLS, one page, 5.5 x 7, personal letterhead, July 24, 1985. Letter to an over-ambitious clergyman. In part: “I must warn you that if you are anxious to read all my books in order you may have tackled more that you really want. I have published 327 books so far. However, only about a third of them are fiction…Still you are not likely to run out in the very near future. My next science fiction novel will be published in about eight weeks and will be entitled Robots and Empire.” In fine condition. RRAuction COA.
