Memo from To: JOSHUA LEDERBERG Joe Fletcher I'd like to have back just the pages with my,notes, plus your final version of the text, to write the introduction. My general policy on remuneration is a "most-favored-nation" approach, but I'm a little puzzled how to apply it here. For the work of reviewing plus writing the introduction my fee to a publisher would be $500 for the primary publicatjion, plus the same for secondary (reissues, paperbacks etc.) In this case I would also settle for 5% of the net royalties, wkie If you think I have added more or less to the value of the product, suggest an alterna- tive figure. Awaiting a healthy delivery from a carefully monitored gestation, Yours PROFESSOR JOSHUA LEDERBERG Department of Genetics School of Medicine Stanford University Stanford, California 94305
