Q. What is the difference between footnotes and a bibliography when you are using the Chicago Manual of Style?
In the Chicago Manual of Style (also known as Turabian), a bibliography is a page on which you list the sources that you have quoted, paraphrased, and/or summarized in the body of your research-based assignment. Bibliographies are optional in the Chicago Manual of Style, but be sure to ask your professor for their requirements.
Footnotes or endnotes are how you give credit to a source in the text itself. You use a superscript number in the text that corresponds to a note with citation information at the end of the document (endnotes) or at the bottom of the page (footnotes). The format of the footnote/endnote citation is a slightly modified version of the citation you list in the bibliography.
"Lincoln's vision of democracy—a vision, it should be noted, strongly shared by Tarbell—could only be saved if the Union was saved."1
