The fifteenth edition of The Chicago Manual of Style is the most extensive revision in twenty years. The Manual--more comprehensive and easier to use than ever before--remains the essential reference for authors, editors, proofreaders, indexers, copywriters, designers, and publishers in any field. Those who work with words know how dramatically publishing has changed in the past decade, with technology now informing and influencing every stage of the writing and publishing process. In creating the fifteenth edition of The Chicago Manual of Style, the renowned editorial staff of the University of Chicago Press drew on direct experience of these changes, as well as on the recommendations of the Manual's first-ever advisory board, composed of a distinguished group of scholars, authors, and professionals from a wide range of publishing and business environments. Every aspect of coverage has been examined and brought up to date--from publishing formats to editorial style and method, from documentation of electronic sources to book design and production, and everything in between. In addition to books, The Chicago Manual of Style now also treats journals and electronic publications. All chapters are written for the electronic age, with advice on how to prepare and edit manuscripts online, handle copyright and permissions issues raised by new technologies, use the latest methods of preparing mathematical copy, and cite electronic and online sources. A new chapter covers American English grammar and usage, outlining the grammatical structure of English, showing how to put words and phrases together to achieve clarity, and identifying common errors. The two chapters on documentation have been reorganized and updated: the first now describes the two main systems preferred by Chicago, and the second discusses specific types of sources and subject matter, with examples tailored to both systems. Coverage of design and manufacturing has been streamlined to reflect what writers and editors need to know about current procedures. And, to make it easier to search for information, each numbered paragraph throughout the Manual is now introduced by a descriptive heading. What would become The Chicago Manual of Style began in the 1890s as a single sheet of typographic fundamentals, prepared by a proofreader at the University of Chicago Press as a guide for the University community. That sheet grew into a pamphlet, and the pamphlet grew into a book--the first edition of the Manual of Style, published in 1906. Nearly a century later the Manual is in use in homes and offices around the world. Clear, concise, and replete with commonsense advice, the fifteenth edition of The Chicago Manual of Style offers the wisdom of a hundred years of editorial practice while including a wealth of new topics and updated perspectives. For anyone who works with words, in any medium, this continues to be the one reference book you simply must have.
