For all books are divisible into two classes, the books of the hour, and the books of all time. Mark this distinction—it is not one of quality only. It is not merely the bad book that does not last, and the good one that does. It is a distinction of species. There are good books for the hour, and good ones for all time; bad books for the hour, and bad ones for all time.
John Ruskin (1819-1900)
