On this site all of Kant’s works, except the Critique of Pure Reason, are cited in the Akademie edition (indicated by AA, followed by volume, page, and when necessary line numbers). The Critique of Pure Reason is cited in the standard way by means of reference to the original pagination of the A (1781) and B (1787) editions, e.g. A67/B92.
All translations from Kant’s works are from the Cambridge edition (1992–), unless indicated otherwise.
Sometimes, authors use additional differentiating abbreviations for Kant’s individual works (again excepting the Critique of Pure Reason). The Siglenverzeichnis of Kant-Studien is adhered to. See here.
