None of the Above
Q. Some authors use italics for unspoken thoughts. What is appropriate when the thought contains the name of a book (which is also italicized)? For example: I wonder where I can get hold of a copy of Julius Caesar. Do I italicize “Julius Caesar,” or do I toggle and make “Julius Caesar” roman type?
A. You can put “Julius Caesar” in roman type (reverse italics) or in quotation marks. This is one reason why putting thoughts into italics is awkward, however. Chicago recommends either no treatment or quotation marks for unspoken discourse. Please see CMOS 13.43.
