Supplemental Elements (Works Cited)

Supplemental elements should be included if they are relevant to the source and/or your use of the source. A supplemental element is placed after Title of Source if it does not pertain to the entry as a whole. Otherwise, it is placed at the end of the Works Cited entry. Occasionally, the supplemental element applies only to the first container and will be placed after the first container and before the second container.Follow a supplemental element with a period. If you need or want to include more than one supplemental element, place a comma between them. Please consult pages 208-9 of the MLA Handbook, Ninth Edition.
