Q. If a book I am citing is in its second edition but was originally translated from German, do I combine all the editions in the bibliography, or do I list all three separately?
A. Cite in full the edition you are using. It’s usually not necessary to add a book’s publishing history to a citation, but if details concerning the first edition or German edition of this book are important or would be useful to your intended reader, by all means include them, either as separate items or as an annotation to the one you used. It’s not practical to make separate listings for all editions of all the books in a bibliography, but depending on your work’s level of scholarship, it might be warranted for books central to your thesis.
