7. Hidden Treasure: The National Library of Medicine
by Michael Sappol
The National Library of Medicine's History of Medicine webpage, featuring images, posters, manuscripts and more dating from the 11th century, is a regular in my browser history, and it was a positive geek thrill for me to learn that Michael Sappol had curated a collection of some of the rarest, and most buried, NLM images. I'm really hoping this one shows up in my stocking. "Grotesque and glowing," Amazon says.
