Research Guides: Chicago Style: Notes vs. Bibliography

Notes

Insert a number when a citation is needed, preferably at the end of a sentence or clause or following quotation marks, if any. Format the number as a superscript (above the line). To format a number as superscript in Microsoft Word:
1. Type the note number, select it, then right-click.
2. Choose the Font option from the list.
3. Under Effects, choose Superscript.)
In the footnotes or endnotes, do not format the note number as superscript.
Always number notes consecutively, starting with 1. Numbers are followed by a period and a space.
When citing the same source more than once, the second and any subsequent (but not consecutive) citations can refer back to the first note. Example: 17. See note 1 above.
Ibid. Use Ibid if two or more consecutive notes refer to the same source and page number (e.g., notes numbered 1, 2, 3). If citing the same source but a different page number, use Ibid., # ( e.g. "5. Ibid., 52.")
If you choose to include a comment in a note, include it after the citation. Example: "5. Mitchell, People in Organizations, 25. This is the text of my comment."
If referencing more than one source in a sentence, insert each superscript at the precise location of the reference, including all citations in the same note. List the citations in the order you referenced them and separate with semicolons, and an "and" before the final one.

A bibliography is a list of references alphabetized by author's last name. If a citation has no author, use the title for alphabetization purposes.
The bibliography is not numbered.
If multiple works have the same author, alphabetize by title. When an author is the sole author of one or more books and a co-author of other books, list the book(s) by the single author before the multi-author book(s).
If you have more than one book by the same author, editor, coauthors, or corporate author in your bibliography, you may use the em dash (long dash) rather than repeating the name(s) in the bibliography. In Microsoft Word, click the Insert tab, click Symbol, More Symbols, Special Characters, and then choose character Em Dash. Follow the dash with the typical punctuation.
