Chicago NB Citation Format

Academic writing style types dictate how work is to be presented and cited. Using the Chicago Style (notes-bibliography or NB) there are two variations depending upon whether the paper is a humanities or science paper. The most common usage of Chicago NB is for History papers, for these, the in-text citation variation using endnotes and footnotes is used. The footnote or endnote begins with the appropriate number followed by a period and then a space. Footnotes are added at the end of the page on which the source is referenced, and endnotes are compiled at the end of each chapter or at the end of the entire document (see Footnotes/Endnotes below for more information).

Using Chicago NB style the citation list is titled Bibliography and references are listed alphabetically by author, with the second and subsequent lines of each reference indented. Where author name is unavailable the reference should begin with the title. Other Chicago rules are double spacing and month abbreviation except for the months of May, June and July. Please refer to the following examples of the Chicago style for various document types.

The Chicago writing style dictates that unpublished interviews and personal conversations be cited in text or in notes rather than in the bibliography. While other styles suggest referencing internet citations in text, Chicago style does not and requires a full bibliographical reference instead.

Footnotes/Endnotes

The Chicago Writing Style dictates that each time a citation is used (through direct quote or paraphrase) a footnote or endnote should be included. The number corresponding to the note with the bibliographic information for that source should be placed within the text at the end of the sentence in which the source is cited. Each time a source is used for the first time in the document all relevant information about the source should be included at the end of the page or chapter. When citing the same source again, the note need only include the surname of the author, the title (or a shortened form of the title) and the page number(s) cited.
