If your citing refers to the work of the author, put the author's name first. If your citing refers to the work of the editor, put the editor's name first:
FIRST EXAMPLE:
Author's last (,) Author's first (.) Book Title (underlined) (.) (Ed.) Editor's name (first, mi, last) (.) Place of publication (:) Publishing company's name (,) Date of print (.)
SECOND EXAMPLE:
Editor's last (,) Editor's first (.,) (ed.) Book Title (underlined) (.) Author's name (first, mi, last) (.) Place of publication (:) Publishing company's name (,) Date of print (.)
Note: "ed." stands for "editor" and must be used before the name on the first example or go after the name in the second example. Use "eds." for multiple editors.
Also note: The second example is correctly capitalized in the use of ed. Rather than the Ed. In the first.
