Why to Cite:
When to Cite:
You should cite a source if you reproduce, quote, paraphrase, or summarize ideas and/or media created by other individuals. When in doubt, cite!
Using Chicago citation style, you should include a note (endnote or footnote) each time you use a source, whether through a direct quote or through a paraphrase or summary. Footnotes will be added at the end of the page on which the source is referenced, and endnotes will be compiled at the end of each chapter or at the end of the entire document.
In either case, a superscript number corresponding to a note with the bibliographic information for that source should be placed in the text following the end of the sentence or clause in which the source is referenced.
The first note for each source should include all relevant information about the source: author’s full name, source title, and facts of publication. If you cite the same source again, the note need only include the surname of the author, a shortened form of the title (if more than four words), and page number(s).
The footnote or endnote itself begins with the appropriate number followed by a period and then a space.
