Tractatus Logico-Philosophicus

Classic precedence trap. The true first publication of the text is German, 1921, in Wilhelm Ostwald's journal 'Annalen der Naturphilosophie' (vol. 14, the final issue, Leipzig), titled 'Logisch-philosophische Abhandlung' - printed without Wittgenstein's corrections and generally regarded as unauthorised. The 1922 Kegan Paul London volume is the first edition in book form / first English edition and is the copy collected as 'the first'; the New York Harcourt Brace 1922 is the simultaneous American issue - name both the 1921 German periodical and the 1922 London book.
