by Chelsea Lee APA Style has special formatting rules for the titles of the sources you use in your paper, such as the titles of books, articles, book chapters, reports, and webpages.
The different formats that might be applied are capitalization (see , section 4.15), italics (see section 4.21), and quotation marks (see section 4.07), and they are used in different combinations for different kinds of sources in different contexts.
They place more emphasis on the enclosed content than commas.
Use parentheses to set off nonessential material, such as dates, clarifying information, or sources, from a sentence.
Use a semicolon to join two independent clauses when the second clause restates the first or when the two clauses are of equal emphasis.
Use a semicolon to join two independent clauses when the second clause begins with a conjunctive adverb (however, therefore, moreover, furthermore, thus, meanwhile, nonetheless, otherwise) or a transition (in fact, for example, that is, for instance, in addition, in other words, on the other hand, even so).
In terms of public legitimacy—that is, in terms of garnering support from state legislators, parents, donors, and university administrators—English departments are primarily places where advanced literacy is taught. Note that commas and periods are placed inside the closing quotation mark, and colons and semicolons are placed outside.
The placement of question and exclamation marks depends on the situation.
In contrast, the titles of works that are part of a greater whole (such as an article, which is part of a journal, or a book chapter, which is part of a book) are not italicized in either place, and only in the text are they put inside quotation marks.
If you are having difficulty determining whether something stands alone (such as a webpage that may or may not be part of a greater website), choose not to italicize.
