In this guide, find guidance on when and how to use Chicago style footnotes and citations. In the future, this guide will also provide help searching for historical resources of academic quality using the library catalog, databases, and area archives.
A footnote is a note at the "foot," or bottom, of a page. In the main text of a document, a superscript number (sitting slightly above the normal line of text) alerts the reader to the existence of a footnote.
Footnotes usually DO NOT replace a bibliography (see this example paper). When in doubt, follow your instructor's rules for formatting.

How to insert the footnote number and footnote:
This will insert a superscript number in the text of your document, and prompt you to write the corresponding footnote at the bottom of the page. Even if you add your footnotes out of order, Word will automatically update the footnote numbers for you.
When do I need a footnote?
Quoting, Paraphrasing, or Summarizing Another Source
In this case, the footnote serves as a citation for the source material you're using. If you're familiar with MLA or APA styles, a footnote is used like an in-text citation: use it to tip off the reader that the information in a sentence is coming from somewhere or someone else.
Elaborating on an Idea or Detail
You can also use a footnote to say more on a topic without interrupting the flow of your paper. When you do this using your own words and thoughts, it is called a substantive note.
If you would like to add commentary to a footnote providing source information (that you have quoted, paraphrased, or summarized), make sure the source comes first. Seperate the citation from your commentary with a period.
