A bookshop is not like a railway booking-office which one approaches knowing what one wants. One should enter it vaguely, almost in a dream, and allow what is there freely to attract and influence the eye. To walk the rounds of the bookshops, dipping in as curiosity dictates, should be an afternoon's entertainment. Feel no shyness or compunction in taking it. Bookshops exist to provide it; and the booksellers welcome it, knowing how it will end.
