In 2013, all year-plans of the curriculum were updated fairly substantially. We expanded dialectic history discussions, and replaced some of the history and literature books, such as the anthologies, with the full book version of the readings. We do not support replaced books on the Book Updates Charts. For this reason, the most current book list at Bookshelf Central will not be an exact match for editions older that 2013. See our handy chart for more information.
