Here is a link for MLA Citation, this might help you with this question as well as question in the future. I will attach part of it in the file. But I would encourage you to save the link as a reference for the future... I know from experience, I use this site all of the time!!
Listing Author Names
Entries are listed by author name (or, for entire edited collections, editor names). Author names are written last name first; middle names or middle initials follow the first name:
Burke, Kenneth
Levy, David M.
Wallace, David Foster
Do not list titles (Dr., Sir, Saint, etc.) or degrees (PhD, MA, DDS, etc.) with names. A book listing an author named "John Bigbrain, PhD" appears simply as "Bigbrain, John"; do, however, include suffixes like "Jr." or "II." Putting it all together, a work by Dr. Martin Luther King, Jr. would be cited as "King, Martin Luther, Jr.," with the suffix following the first or middle name and a comma.
More than One Work by an Author
If you have cited more than one work by a particular author, order the entries alphabetically by title, and use three hyphens in place of the author's name for every entry after the first:
Burke, Kenneth. A Grammar of Motives. [...]
---. A Rhetoric of Motives. [...]
When an author or collection editor appears both as the sole author of a text and as the first author of a group, list solo-author entries first:
Heller, Steven, ed. The Education of an E-Designer. 
Heller, Steven and Karen Pomeroy. Design Literacy: Understanding Graphic Design.
Work with No Known Author
Alphabetize works with no known author by their title; use a shortened version of the title in the parenthetical citations in your paper. In this case, Boring Postcards USA has no known author:
Baudrillard, Jean. Simulacra and Simulations. [...]
Boring Postcards USA. [...]
Burke, Kenneth. A Rhetoric of Motives. [...]
