For example:
Kelson, John. “Allegory and Myth in ‘The Cherry Orchard’,” Western Humanities Review 13, No. 3 (Summer 1959): 321-24.; excerpted and reprinted in Twentieth-Century Literary Criticism, vol. 55, ed. Marie Lazzari (Detroit: The Gale Group, 2001). 42-44.
Notice that the original critical essay written by John Kelson on Anton Chekhov’s play, “The Cherry Orchard” appeared in Western Humanities Review in 1959. However, since you did not have the original essay, but rather read part of the essay in Twentieth-Century Literary Criticism, you must include that information in your citation.
