My bookshelf style, in haiku because haiku* are mercifully short, unlike novels:
Random objects used
Non-existent or obscure.
(Someone had to provide a place in the world where a Brent Weeks novel snuggles up against the Ad Herennium, Plato touches Mockingjay, and Austenland calmly sits beside Hamlet.)
*This is the proper plural form. I checked the OED. And the OED knows.
