Final answer:
In MLA style, the source title is used in an in-text citation when the source has no identifiable author, and the title is quoted or italicized depending on the length of the work.
Step-by-step explanation:
In MLA style, an in-text citation may need to include the source title if the source does not have an identifiable author. When a source lacks an author, it is often recommended to use the title of the work in a signal phrase, or a shortened title within parentheses, in place of the author's name in the in-text citation. The title should be in quotation marks if it's a shorter work (like an article) or italicized if it is a longer work (like a book or journal).
Here are examples of in-text citations without an author:
- For an article: ("Shortened Article Title" page number).
- For a book: (Italicized Book Title page number).
Note that in-text citations are designed to guide the reader to the complete citation on the Works Cited page, where full details of the source are provided.
