In a town like London there are always plenty of not quite certifiable lunatics walking the streets, and they tend to gravitate towards bookshops, because a bookshop is one of the few places where you can hang about for a long time without spending any money.George Orwell, “Bookshop Memories” in Fortnightly (November 1936)
A good bookshop is just a genteel Black Hole that knows how to read.Terry Pratchett, Guards! Guards!
