This eighth edition works according to a couple of core principals, one of which is: "make your documentation useful to readers" (MLA Handbook Eighth Edition 4). The goal is to make the citations clear and easy for readers to understand and locate. MLA does have rules for citation, but they can be altered to fit the situation as needed. The of the MLA handbook was published in 2016.
