Final answer:
The title of larger works should be in italics, such as for books and movies, while shorter works like articles and poems use quotation marks.
Step-by-step explanation:
With larger works, the title should be in italics. Titles of long works such as books, movies, and TV series are italicized because they are published, produced, or released separately from other works. For example, we use italics for the titles of novels like The Great Gatsby and films such as Star Wars. In contrast, titles of shorter works like articles, short stories, and poems are placed in quotation marks. For instance, an article titled "How Technology is Changing Education" would be enclosed in quotation marks.
When citing a work in a paper where the author is unknown, you can use the work's title in a signal phrase or in parentheses. Moreover, if you need to modify a quotation for clarity, brackets [] are used to indicate any changes made to the original text.
