The laugh for readers comes as Stephen Strange and Zelma Stanton, a librarian, are investigating an otherworldly (what else?) disturbance at Strange's mansion, the Sanctum Sanctorum.
Of course, it's not Strange's fault. As Dr. Venkman would say, "no human being would stack books like this."
But I reckon that when you have a library filled with arcane and occult tomes, some of which have a mind of their own, these sorts of shenanigans will happen on occasion.
As an aside from the comic-book sorcery, if you're interested in how actual humans have organized and shelved their books throughout history, I highly recommend The Book on the Bookshelf by Henry Petroski.
1. I've sort of reverted to age 12 and have been reading a number of new comics lately. Other than Doctor Strange, I'm also following Black Panther (by Ta-Nehisi Coates); Ms. Marvel; Patsy Walker, A.K.A. Hellcat!; and Providence (by Alan Moore). In addition, I'm working through late Silver/early Bronze volumes of The Avengers, Sub-Mariner, Man-Thing and Doctor Strange.
