How do I create an MLA header for a paper with multiple authors?
If you’re working on a group project and therefore need to list multiple authors for your paper, MLA recommends against including a normal header. Instead, create a separate title page.
On the title page, list each author on a separate line, followed by the other usual information from the header: Instructor, course name and number, and submission date. Then write the title halfway down the page, centered, and start the text of the paper itself on the next page.
