To go around the world checking out these book stores (never you mind the small issue of actual storage at home...) would be an absolutely dream trip.
Especially this one.
There is a bookstore like this near Leicester Square, it is just brilliant, full of nooks and crannies, full of second hand books. Next time I get a chance, will go there and poke around, smell the wonderful smell of books and forget all about time till the chap comes and pokes me to go home.
Ah! so many books and so little time.
