An undertaking such as the publication of The Chicago Manual of Style, which strives to codify the best practices of an institution and an industry, must be an effort of many hands and many voices if it is to succeed. This edition has benefited from the carefully crafted recommendations—some broad, some minute, all essential—of a legion of publishing professionals. At the same time, it was equally essential that those recommendations be compared, vetted, and applied in a consistent manner and with a clear vision, a challenging task performed in exemplary fashion by this edition’s principal reviser, Russell David Harper.
       A preliminary outline as well as the entire penultimate draft of the manuscript was read and commented on by an advisory board representing various communities of readers:

       On a final note, this edition is in many ways most indebted to Catharine Seybold (1915–2008) and Bruce Young (1917–2004), who compiled the landmark twelfth edition of this manual as well as the thirteenth, to John Grossman, who compiled the fourteenth edition, and to Margaret Mahan, who was responsible for the fifteenth. It is to their high standard for what has come to be known as “Chicago style” that we have looked in preparing this, the sixteenth edition of the manual.
