 Nietzsche’s published works are cited by his original section numbers (or larger part plus section numbers together), which are the same in all editions. Citations follow the North American Nietzsche Society system of abbreviations for reference to English translations. For each work, the primary translation quoted in the entry is listed first, followed by other translations that were consulted. (N.B.: the entry occasionally departs from the quoted translation, usually in the direction of greater literalness, without separate notice.) Original date of German publication is given in parentheses at the end of each entry.
