I rarely buy books. Instead, I use the LAPL's reserve system. I put a hold on a book, and (usually) within days the requested item is at my branch.
Today's delivery was one of the better ones:
The following item(s) you requested are
being held for you at [Branch]:
Nietzsche, Friedrich (Ed. Clark, Leiter)
Rama, Marie; Mariani, John
Grilling for Dummies
I'm thinking Nietzsche would not have approved of the company he was keeping.
