Headlines and Titles of Works
Q. When working in an electronic format that does not allow italics, how should you treat the titles of books?
A. If your text is mainly meant to convey information, you can indicate italics _like this_ or <italic>like this</italic> or <i>like this</i>. If you want the text to display nicely, some applications allow you to use color or boldface or underlining. A last resort is to use all caps or quotation marks.
