The Intelligent Investor

No book-club issue is documented for the 1949 first. The dominant trap is revised editions and modern reprints: later Harper, Harper & Row and HarperBusiness printings carry the 1949 copyright date on the copyright page alongside the later revision date, which routinely misleads sellers into cataloguing them as 1949 firsts. Read the Harper letter code, not the copyright year. Caveat on strength of evidence: the "D-Y" code and the Harper code table are firmly corroborated (the table is independently validated by fedpo's worked examples), but the "Editor of Barron's" and 7553 front-flap jacket points rest on dealer descriptions from two firms rather than a formal bibliography.
