The first note citing a particular source must include the full citation.

In books, note numbers return to 1 at the beginning of each chapter. Footnotes and endnotes should be ordered consecutively, starting from 1, throughout a paper, article, or chapter.The first line of each footnote or endnote (and only the first line) should be indented one half inch from the left margin.It is followed by a period, a space, and then the citation. In the footnote or endnote itself, the number is not superscript.For information on placement of superscript numbers, see The Chicago Manual of Style, 14.26.According to Cranston, Rousseau was "the least academic of modern philosophers."² This number should correspond to a footnote or endnote which cites the source being referenced. After you have quoted, paraphrased, or summarized someone else's work, place a superscript number at the end of the sentence or clause.

Footnotes are generally most popular, as they are easier to reference. Also, consult your instructors, as they may prefer one over the other. For the pros and cons of using each, see The Chicago Manual of Style, 14.44 and 14.45.
