Final answer:
The title of shorter works should be placed in quotation marks, not italics, parentheses or brackets.
Step-by-step explanation:
With shorter works, the title should be placed in quotation marks. This rule applies to titles such as articles in periodicals, short stories, short poems, essays, songs, episodes of TV or radio programs and series, and book chapters. When the author of a work is unknown, use the work's title in a signal phrase or a shortened version of the title in parentheses and put the title in quotation marks for articles, while using italics for book or journal titles.
