. @l § THE ROCKEFELLER UNIVERSITY pro bono humani generis 1230 YORK AVENUE - NEW YORK, NEW YORK 10021-6399 Joshua Lederberg UNIVERSITY PROFESSOR September 23, 1999 Dr Phil Manning USC School of Medicine fax 323:442-2152 Dear Phil I sent you an ms. for Passion-2 a few weeks ago. I don’t recall any copyright paper work. N.B. attached, my friend Amy Friedlander would like to use similar text for the online magazine she edits. I still offer you the article, but hope you will have no objection to my reserving the right for a) this online publication b) presentation on the web site for my archives. As a rule, I’d be glad to hold back for, say one year, after primary publication date, but that would be moot. See http://profiles. NLM.nih.gov/BB I can see only advantage to your getting the advertisement that goes along with this free sample. Please advise Amy how you would like Passion-2 referred to. What is your email? /Joshua Lederberg Professor-emeritus email: lederberg @mail.rockefeller.edu
