Tractatus Logico-Philosophicus

Not a book-club title. Later-issue tell within the 1922 first edition: advertisements (often later-dated) bound at the rear indicate a later binding-up of the first-edition sheets. Distinct later editions to avoid confusing with the first: the 1933 corrected second edition, and the wholly different 1961 Pears & McGuinness translation (Routledge & Kegan Paul).
