Examine how the play is divided and follow general guidelines for play in-text citations. If numbers are provided, "give the numbers of lines, acts, and scenes, or chapters and verses," say Cheryl Glenn and Loretta Gray, authors of "Hodges Harbrace Handbook."
Place the act number, the scene number and the line number(s) inside the parenthetical citation at the end of the sentence where the quote appears: Desdemona pleads to Othello, "Kill me tomorrow; let me live tonight" (5.2.80).
Cite page numbers if the play does not note lines, acts and scenes. According to the "MLA Handbook for Writers of Research Papers" by Joseph Gibaldi, indent dialogue one inch from the left margin and capitalize the characters' names:
EVELYN. Art is visceral
ADAM. So, I guess I didn't feel it, then. (26)
Be aware that information provided in a parenthetical citation exists to direct readers to a corresponding entry on a Works Cited page. Providing complete documentation about each source cited in the form of a works cited entry allows readers to locate the source for themselves.
