In the 1890s, a proofreader at the University of Chicago Press prepared a single sheet of typographic fundamentals intended as a guide for the University community. That sheet grew into a pamphlet. The pamphlet grew into a book. The 1st edition of the Manual of Style published in 1906. Now The Chicago Manual of Style is the essential reference for authors, editors, proofreaders, indexers, copywriters, designers & publishers in any field.
