The general format below refers to a book with three or more authors.
If you are dealing with a book that has three to five editors instead of authors, you would simply insert the names of the editors into the place where the authors' names are now, followed by "(Eds.)" without the quotation marks (as per the example). The rest of the format would remain the same.
