Here's a tantalizing preview [PDF] of The Art and History of Globes, a massive, gorgeous art-book tracing the history of globes. Written by Sylvia Sumira, forthcoming from the University of Chicago Press in March. The globes pictured run back 400 years, and come from the collection of the British Library. As Levi from the press says, "they're amazing: beautifully designed and drawn, intricate, strange–just incredible objects."
(Thanks, Levi!)
