Modern Language Association is covered on chapter 47 of the book, and even though I'm sure there is a more recent edition I am just amazed at the level of detail that MLA is covered. Take for example, work cited models, it has 67 examples alone which cover Books, Periodicals, Electronic sources, and Other print and non-print sources. As well as an additional 71 pages that cover graphs, and go into detail of each area such as Journals, and Magazines which would be under Periodicals, it also covers paper positioning and so forth. I can only imagine what else has been added if there is indeed a more recent edition(s).
I wonder if the Modern Language Association headquarters in New York has someone constantly evaluating and adding rules, regulations etc.
MLA is insane.
