Full-text titles, such as books or newspapers, should be italicized. Short work titles, such as poems, essays, short tales, or chapters, should be surrounded by quotation marks. If the name of the book series is italicized, titles of books that are part of a larger body of work may be put in quotation marks. For example: "The Iliad": An Epic Poem by Homer or "The Epic of Achilles"?
Most subtitle pages contain only one type of title; that is, they offer only one way to format a title. However, a few subtitle pages include two types of titles: original and translated. With original titles, the translator creates a new title for the work being translated; with translated titles, the translator uses a preexisting title that he or she has chosen carefully.
Original title: The Adventures of Tom Sawyer Author: Mark Twain Translated title: Tom Sawyer Abroad Publisher: Oxford University Press
Translated title: Dr. Zhivago Author: Boris Pasternak Year published: 1957
Long titles, such as novels, movies, or record albums, should be italicized in general. For the names of shorter pieces of work, such as poems, essays, book chapters, songs, TV programs, and so on, use quote marks. Punctuation depends on whether the title is being quoted elsewhere in the text.
Poems, essays, book chapters, music, and television shows should all have their titles in quote marks. Sometimes only the title line of a poem, song, or essay is quoted; in these cases, period punctuation should be used instead of full stops.
Underlining the title of a work of art is common practice when quoting from it. This is particularly true of books, magazines, and newspapers. The title will usually appear on the first page of the source material or in an introductory section called "Title Page." An example can be found in this photo from the National Portrait Gallery in London:
They also quote from artists' letters, statements, and reviews of their work. This is done to show that they are referring to something other than your average person. Underlining key words in titles is another common practice; for example, "The Great Gatsby" or "Ulysses". These items are used for comparison or contrast with your own work; therefore, they should be highlighted in some way for clarity purposes.
Finally, underlining the title of a film or album is useful when listing information about its production; for example, "A Fish Called Wanda" (1988) or "Abbey Road" (1969).
Italicized book, play, film, magazines, databases, and online titles are italicized. 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. At times, titles may contain other titles. For example, a book about George Washington might have the title IV: CV (1754-1799).
Books, newspapers, and magazines use titles to identify their sources. In books, the author's name is usually listed first, followed by an abbreviated title indicating the source. The title can be as short as one word or it can be the entire title of the book. Films and television shows also have titles. These tend to be shorter than books' titles.
Newspapers and magazines use titles to distinguish articles in their publications. For example, an article in the New York Times entitled "Why I Am Not A Christian" would have the title in quotes because it is a unique piece. A magazine such as Vanity Fair could have multiple articles with different titles; for example, "The Day After America Elected Donald Trump" and "Has Democracy Failed America?" would both be titled articles but they would represent two different subjects covered by the magazine over time.
Titles can be used to differentiate people's work. For example, Thomas Edison invented the phonograph. However, who invented the record player? Edward Dolby.
