The Chicago Manual of Style, 17th Ed.

This weighty volume is the essential reference for all who work with words—writers, editors, proofreaders, indexers, copywriters, designers, publishers, and students. Discover who Ibid is, how to deftly avoid the split infinitive, and how to format your manuscripts to impress any professor or editor. (No, putting it in a blue plastic folder is just not enough.) Provides excellent refinement to the writing skills learned in the IEW program.
