In MLA 7 and 8, titles of books, journals, websites, albums, blogs, movies, tv shows, magazines, and newspapers should all be italicized. In APA, use italics for titles of books, scholarly journals, periodicals, films, videos, television shows, and microfilm publications. Quotation marks or italics are not required for articles, webpages, songs, episodes, etc. Think of it this way: if the source is a collection of smaller sources or could be cited on its own, it should be in italics.

When to Punctuate Titles in Italics or Quotes
Italics and underlining are like flashers on road signs. They make you take notice. Italics and underlining can be used interchangeably, although usually underlining is used when something is either hand written or typed; if using a computer you can italicize. If you start using italics, don't switch to underlining within the same document.
You should follow the rules dictated by the guidelines. For AP style, however, you never use italics for pieces of work — no matter the length. Additionally, the APA style neither uses quotation marks or italics for shorter works. Instead, it expects them to be written as normal text. Sometimes, the choice of style may be up to you as a writer.
