Em "The Haunted Bookshop" (Christopher Morley, 1919) o protagonista encontra uma livraria escondida em Brooklyn em Nova Iorque com o seguinte letreiro:

PARNASSUS AT HOMER. AND H. MIFFLINBOOKLOVERS WELCOME!THIS SHOP IS HAUNTED


THIS SHOP IS HAUNTED by the ghosts of all great literature, in hosts;
We sell no fakes or trashes.
Lovers of books are welcome here,
No clerks will babble in your ear,
Please smoke--but don't drop ashes!
----
Browse as long as you like.
Prices of all books plainly marked.
If you want to ask questions, you'll find the proprietor where the tobacco smoke is thickest. We pay cash for books.
We have what you want, though you may not know you want it.

Malnutrition of the reading faculty is a serious thing.
Let us prescribe for you.
