Italicize work titles (books, magazines, newspapers, movies, plays, and CDs). For shorter works, use quote marks (book chapters, articles, poems, and songs). Sometimes you'll find yourself trapped and unsure of what punctuation to use. In that case, follow the style of the work in question.
Long titles, such as novels, movies, or record albums, should be italicized in general. Poems, essays, book chapters, music, and television shows should all have their titles in quote marks. End quotes (") are used to indicate where one word ends and another begins.
Italicizes the titles of books, plays, films, magazines, databases, and websites. If the source is part of a larger work, put the title in quotation marks. Articles, articles, chapters, poems, websites, songs, and speeches are all surrounded by quote marks. Titles can sometimes contain additional titles. For example, a novel may have a subtitle as well as a title. A subtitle usually comes after the main title but can be placed before or after it. Subtitles often explain or highlight aspects of the story.
Subtitles can be used to distinguish copies of a book that were printed with different layouts or designs. For example, one copy might have a cover design that includes colored plates while another has only black-and-white drawings. The subtitles would reflect this difference and people would know which version to get if they wanted to own a complete set. Subtitles can also be used to distinguish editions of a book that are simply not identical other than the fact that they both bear the same title. For example, there might be an edition that is signed by the author and another that is not. These would be two separate titles because even though they both fit on the spine of the book, they provide information about different aspects of the work.
Titles can be used to identify parts of larger works, such as chapters and sections. These should always be written in sentence case.
Full-text titles, such as books or newspapers, should be italicized. Poems, articles, short tales, and chapters should have their titles in quotation marks. If the name of the book series is italicized, titles of volumes that create a greater body of work may be put in quotation marks. For example: "The Iliad" and "The Odyssey".
Titles used to identify people, such as president or professor, do not require punctuation. The title should be listed first followed by the author's last name (or sometimes only the last word) in sentence case. For example: President Obama, John Smith.
General rules for styling names can be difficult to apply because they depend so much on context. For example, if the name appears in a quoted sentence, it should be formatted as shown above. But if the name appears in its own sentence, no punctuation is needed. Names can also be found in lists of things like names of states or countries. In this case, too, no punctuation is needed. Finally, if the name appears in academic writing with a surname following it, then again, no punctuation is required.
Overall, use common sense and be consistent. If you decide to use punctuation, keep in mind that periods are optional at the end of sentences, acronyms, and proper names.
If the source is self-contained and independent, italicize the title. Treat entries in dictionaries as titles.
For example, if the article you are referencing was titled "The American Dream is dead", then you would write: "The death of the American Dream".
If the source is part of a larger work, use parenthesis to enclose the title of the article. For example, if the article you are referencing appeared in USA Today, use parentheses to indicate this: "(USA Today)".
Put the title in quotes within the reference itself if it is not italicized or in parentheses. For example, if the article you are referencing was called "A Dictionary of Modern English Usage" then write: "A dictionary of modern usage".
Do not use periods after titles of publications, except after abbreviations such as "b." for "brother" or "f." for "father". Periods are used after given names and surnames: "John Doe is the author of..."
Use full stops (periods) after titles of books, movies, and recordings that are more than one sentence long.
