If you cite the same source again, or if a bibliography is included in the work, the note only needs to include the surname of the author, a shortened form of the title (if more than four words), and the page number(s).
This manual, which presents what is commonly known as the "Turabian" citation style, follows the two CMOS patterns of documentation but offers slight modifications suited to student texts.
The Chicago Notes and Bibliography (NB) system is often used in the humanities to provides writers with a system for referencing their sources through the use of footnotes, endnotes, and through the use of a bibliography.
(CMOS) covers a variety of topics from manuscript preparation and publication to grammar, usage, and documentation, and as such, it has been lovingly dubbed the “editor's bible.” The material on this page focuses primarily on one of the two CMOS documentation styles: the Notes-Bibliography System (NB), which is used by those working in literature, history, and the arts.
The other documentation style, the Author-Date System, is nearly identical in content but slightly different in form and is preferred by those working in the social sciences.
You can find it in chapters 16 and 17 of the Turabian manual.
Chapters 18 and 19 give examples for the Author-Date style.
In the NB system, the footnote or endnote itself begins with the appropriate full-sized number, followed by a period and then a space.
In the NB system, the bibliography provides an alphabetical list of all sources used in a given work.
Though the two systems both convey all of the important information about each source, they differ not only in terms of the way they direct readers to these sources, but also in terms of their formatting (e.g., the position of dates in citation entries).
