When referencing a translated book, chapter, or article, you must give information sufficient for the reader to find both the original untranslated work, as well as the translated work.
You reference a translated work by listing (1) the name of the original author(s), (2) the date that the translation was published, (3) the title of the book or paper, (4) the name of the translator(s) in parentheses, (5) the source information for the translation, (6) the location and name of the publisher of the translation, and (7) the date that the original work was published in parentheses.
If an entire book is translated and republished, the title of the book is italicized. If a chapter or article is translated, the title of the book or journal in which the translation is published is italicized.
