I love the Chicago Manual of Style notes-bibliography referencing style, although I treat it as the lesser of many evils. For instance, this has always bugged me: why is it that in footnotes, the page numbers of books are preceded by a comma:
Michael Pollan, The Omnivore’s Dilemma: A Natural History of Four Meals (New York: Penguin, 2006), 99–100.
But the page numbers of journal articles are preceded by a colon?
Joshua I. Weinstein, “The Market in Plato’s Republic,” Classical Philology 104 (2009): 440.
I like the colon, since it clearly shows that the next section of the reference is from within the reference (i.e. it is a specific page number). But I'm going to get raised eyebrows if I use colons everywhere in my footnotes. So why the discrepancy in the first place?
