Critik der reinen Vernunft (Critique of Pure Reason)

The Riga 1781 German printing (the "A" edition) is the true first. The substantially revised second edition (Riga: Hartknoch, 1787, the "B" edition) is separately and seriously collected as the first appearance of the rewritten Transcendental Deduction and the Refutation of Idealism; modern scholarly texts print A and B in parallel, and collectors of the work generally want both. The census claim that Meiklejohn (Bohn, 1855) is the first English translation is INCORRECT and is corrected here: the first English translation is Francis Haywood's "The Critick of Pure Reason" (London: William Pickering, 1838), with Haywood's revised second edition in 1848. J. M. D. Meiklejohn's translation (London: Henry G. Bohn, Bohn's Philosophical Library, 1855) is the second English translation — it is the common Victorian reading copy and the realistic English-market form, but it is not the first English appearance.
