Final answer:
In APA format, italics are used for the titles of long works such as books, plays, movies, and TV series. Titles of shorter works are placed in quotation marks. Italics are also used when the author is unknown and in the titles of journals and periodicals in APA citations.
Step-by-step explanation:
In APA format, italics are used for the titles of long works that are published, produced, or released separately from other works. Some examples of these works include:
- Books
- Long poems
- Plays
- Movies
- TV or radio programs and series
Additionally, when the author of a work is unknown, italics are used for the title of the work in a signal phrase, or a shortened version of the title is placed in parentheses. Titles of long works are italicized while shorter works, such as article titles, are placed in quotation marks. For instance, if quoting from a book in APA style, the title should be in italics as in the example: "The Call of the Wild sets the contrasting tone..." (London, 1903, p. 1).
Journals and periodicals also follow this rule, with the title of the journal being italicized and significant words capitalized, as shown in APA citations.
