Libraries are magical places. But what if they're even more magical than we know? In Cyrille Martinez's library, the books are alive: not just their ideas or their stories, but the books themselves. Meet the Angry Young Book, who has strong opinions about who reads what and why. He's tired of people reading bestsellers, so he places himself on the desks of those who might appreciate him. Meet the Old Historian who mysteriously vanished from the stacks. Meet the Blue Librarian, the Mauve Librarian, the Yellow Librarian, and spend a day with the Red Librarian trying to banish coffee cups and laptops. Then one day there are no empty desks anywhere in the Great Library. A great horde of student workers has descended, and they will scan every single book in the library: the much-borrowed, the neglected, the popular, the obscure. What will happen to the library then? Will it still be necessary? The Dark Library is a theoretical fiction, a meditation on what libraries mean in our digital world. Has the act of reading changed? What is a reader? A book? Martinez, a librarian himself, has written a love letter to the urban forest of the dark, wild library, where ideas and stories roam free.
