The MLA Handbook does not provide guidelines for formatting a thesis or dissertation—or for preparing the parts of such a project, like a preface, dedication, or acknowledgments page—because most schools maintain their own formatting requirements. Although the MLA Style Manual and Guide to Scholarly Publishing, out of print since 2016, summarized some of these requirements, it did so only in a very general way. 

Writers of theses and dissertations should follow any guidelines their schools provide. If a school does not provide such guidelines, a successfully defended dissertation in the writer’s department might provide an example to follow.
