I just stumbled on this little gem, which so far holds the record of slash usage in a book subtitle:
I, California: the Occasional History of a Child Actress/Tap Dancer/Record Store Clerk/Thai Waitress/Playboy Reject/Nightclub Booker/Daily Show Correspondent/Sex . . . Character/and Whatever Else.
If the slashes have piqued your interest, you can learn more about Stacey Grenrock Woods' new book in this post at Mediabistro's Galleycat.
Bet you never thought you'd see girlie photos on the Heymarci blog.
