A reference, explanation, or comment1 placed below the main text on a printed page.
Examples and Observations:
- "Footnotes: virtues. Readers of scholarly works usually prefer footnotes for ease of reference. Where the notes are closely integrated into the text and make interesting reading, they belong at the foot of the page. . . .
"Footnotes: vices. In a work containing many long footnotes, it may be difficult to fit them onto the pages they pertain to, especially in an illustrated work."
(Chicago Manual of Style, Univ. of Chicago Press, 2003)
- "Footnotes are used to provide additional content or to acknowledge copyright permission status.
"Content footnotes supplement or simplify substantive information in the text; they should not include complicated, irrelevant, or nonessential information. . . .
"Copyright permission footnotes acknowledge the source of lengthy quotations, scale and test items, and figures and tables that have been reprinted or adapted."
(Publication Manual of the American Psychological Association, 6th ed., 2010)
- Content Footnotes
"What, after all, is a content footnote but material that one is either too lazy to integrate into the text or too reverent to discard? Reading a piece of prose that constantly dissolves into extended footnotes is profoundly disheartening. Hence my rule of thumb for footnotes is exactly the same as that for parentheses. One should regard them as symbols of failure. I hardly need add that in this vale of tears failure is sometimes unavoidable."
(Paul Robinson, "The Philosophy of Punctuation." Opera, Sex, and Other Vital Matters. Univ. of Chicago Press, 2002)
- Footnote Forms
All notes have the same general form:
1. Adrian Johns. The Nature of the Book: Print and Knowledge in the Making (Chicago: University of Chicago Press, 1998), 623.If you cite the same text again, you can shorten subsequent notes:
5. Johns. Nature of the Book, 384-85.(Kate Turabian, A Manual for Writers of Research Papers, Theses, and Dissertations, 7th ed. Univ. of Chicago Press, 2007)
- The Disadvantages of Footnotes
"More than one recent critic has pointed out that footnotes interrupt a narrative. References detract from the illusion of veracity and immediacy . . . . (Noel Coward made the same point more memorably when he remarked that having to read a footnote resembles having to go downstairs to answer the door while in the midst of making love.)"
(Anthony Grafton, The Footnote: A Curious History. Harvard Univ. Press, 1999)
"Footnotes, the little dogs yapping at the heels of the text."
(attributed to William James)
1 "The footnote has figured prominently in the fictions of such leading contemporary novelists as Nicholson Baker2, David Foster Wallace3, and Dave Eggers. These writers have largely revived the digressive function of the footnote."
(L. Douglas and A. George, Sense and Nonsensibility: Lampoons of Learning and Literature. Simon and Schuster, 2004)
2 "[T]he great scholarly or anecdotal footnotes of Lecky, Gibbon, or Boswell, written by the author of the book himself to supplement, or even correct over several later editions, what he says in the primary text, are reassurances that the pursuit of truth doesn't have clear outer boundaries: it doesn't end with the book; restatement and self-disagreement and the enveloping sea of referenced authorities all continue. Footnotes are the finer-suckered surfaces that allow tentacular paragraphs to hold fast to the wider reality of the library."
(Nicholson Baker, The Mezzanine. Weidenfeld and Nicholson, 1988)
3 "One of the odd pleasures in reading the work of the late David Foster Wallace is the opportunity to escape from the main text to explore epic footnotes, always rendered at the bottoms of pages in thickets of tiny type."
(Roy Peter Clark, The Glamour of Grammar. Little, Brown, 2010)
