The general format below refers to a book with more than three authors.
If you are dealing with a book that has more than three editors instead of authors, insert the names of the editors into the place where the names of the authors are now, followed by a comma and the word "eds." without the quotation marks (as per the example). The rest of the format remains the same.
1. Author First Name/Initial Surname et al., Book Title: Subtitle (Place of Publication: Publisher, Year), page #.
