Critik der reinen Vernunft (Critique of Pure Reason)

No 18th-century book-club analogue exists. Reprint tells: a title reading "Kritik" rather than "Critik", or bearing any "Auflage" statement, is not the 1781 sheet. Bohn's Philosophical Library issues from 1855 and the later Everyman and Macmillan Meiklejohn printings are translations reset from the 1787 B text, not editions of the German first; the Kant-Gesellschaft and Akademie-Ausgabe texts are 20th-century scholarly reprints. Every German edition after 1787 follows the reset B text, so a German-language copy dated after 1781 is by definition not the A edition.
