The Feynman Lectures on Physics (3 vols.)

Richard P. Feynman, Robert B. Leighton, Matthew Sands · Addison-Wesley (Reading, MA) · 1963 (Vol I), 1964 (II), 1965 (III)

True first is the Addison-Wesley US edition; sets must be assembled with each volume in first printing (commonly mismatched). The much later 'Definitive Edition' (2005) and 'New Millennium Edition' are corrected reprints, not firsts. Three-volume first-printing sets in the original slipcase/binding are scarce.
