The endnote/footnote and bibliography styles for references are featured in Doc's guide, the author-date system is not covered. The guide was revised in Fall 2017, updated to the current Turabian manual (2013) and Chicago Manual of Style (2010). MLA Handbook? The 2016 version (8th ed.) is no longer a handbook for "Writers of Research Papers." It is just the MLA Handbook (period). The editors argue, "today academic work can take many forms other than the research paper" so a handbook for research papers is too limiting. The style also insists on references to unrecoverable sources (letters, emails, missing web pages), unacceptable in serious scholarship. The "container" system for references is too tedious to be useful, other changes do not add clarity.
