How do I order my references?
In alphabetical order, by author last name.
Different sources, same first author?
List by date. List any n.d.s first.
Then list from oldest to newest.
What if there is no author?
Order alphabetically, by title.
Are you sure there isn't a group author?
Lots of authors?
References should include 20 authors. With two or more authors, include & before the last author.
