Remember that people used to type their work or write it longhand. When titles needed to be italicized, italics were represented by underlining. These days, many people avoid underlining to minimize confusion between words that are underlined and hyperlinks. 1) Underlining and italics serve the same purpose. Never do both. Do NOT use quotation marks, underline, or italics together. 2) For any work that stands on its own, you should use italics or underline. (Stories or chapters from within a book are considered PARTS of the book.) 3) A work that is part of a larger work goes in quotation marks.
