Work by two authors

The unemployed of Denmark have had the right to request job related activities such as training or publicly supported work, but that right has recently become an obligation (Rosdahl and Weise 160).

Work by three or more authors
Cite all authors the first time the reference occurs; in subsequent citations, include only the last name of the first author follow by 'et al.'

Electronic, Audio, and Visual Sources
These sources are cited in the typical author-page number style with one difference: when an Internet site, movie, recording, etc. does not have page numbers, offer other location information such as screen, track, or paragraph (par.) number, or provide a time frame (30th minute).

Because of Greece's physical characteristics-its jagged coast made almost all settlements within 40 miles of the sea-the ancient Greeks relied on the sea for most long-distance traveling (Martin sec. 2.4).

Multivolume Works

Most of Plato's ideas about love are recorded in the Symposium (Singer 1: 48), while Ficino's are mainly to be found in the Commentary on Plato's Symposium (Singer 2: 168).

Works listed by title

Critics have recently taken exception to the decision by the Joliet City Council to allow a new minor-league baseball stadium to be named after a local hospital ("This stadium available").

Note: include the page number unless the work cited is a very short one, such as a newspaper article or encyclopedia entry.

Works by corporate authors

Between 1970 and 1994, expenditures on information processing equipment rose at an inflation-adjusted average annual rate of 9.7 percent (Natl. Research Council 25).

Two or more works by the same author

All of Christian mysticism grew out of St. Augustine's discussions of the eros theme (Singer, The Nature of Love 170).

St. Augustine clearly distinguished between earthly and divine love, but he did not denigrate all forms of self-love (Singer, The Pursuit of Love 74).

Indirect quotations

John Evelyn described London's churchyards as being filled with bodies "one above the other, to the very top of the walls, and some above the walls" (qtd. in Clayton 14).

Use this form to cite a quotation that was identified by its being a quotation in another (not the original) source.

Classic Literary and Religious Works
When citing a classic work that is available in multiple editions, try to provide location information (chapter, section, verse, etc.) beyond the page number.

Wittgenstein writes, "the philosopher's treatment of a question is like the treatment of an illness" (Wittgenstein 91; sec. 255).

When citing plays, poems or the bible, omit page numbers and cite by division (act, scene, canto, book, part, etc.) and line. Titles of famous works are often abbreviated.

Queen Gertrude is concerned about Hamlet's great distress over his father's death, saying "Do not for ever with thy vailed lids / seeks for they noble father in the dust: / thou know'st 'tis common; all that lives must die..." (Ham. 1.2.70-72).
