MLA paper format outlines the proper way to format and structure a paper. It includes a title page with the author's name, professor's name, course, and date. The body of the paper uses Times New Roman 12-point font, double spacing, 1-inch margins, and paragraph indents. A works cited page lists all sources in alphabetical order following the MLA citation style guide. MLA format is commonly used in the humanities for presenting research and citing sources.
