 :Do You Believe in Magic? The Sense and Nonsense of Alternative Medicine →  – WP:SUBTITLES neither discourages nor encourages using subtitles, depending on WP:AT policy. To be consistent with other articles named "Do You Believe in Magic", "(book)" is needed. Of course, if a question mark is unneeded, then  will do. If the title with subtitle and the title without it are commonly used, then we should implement WP:DIVIDEDUSE and other applicable policies and guidelines like WP:CONSISTENCY.
