''Gray's Anatomy of the Human Body'' was first published in 1858 by Henry Gray. It's been built on ever since. Currently in its [[LongRunners 40th edition]], it's considered the authoritative sourcebook for pretty much all anatomical issues.

The characters on the show '''''Series/GreysAnatomy''''' might have read it during med school, but no one knows due to all the [[EverybodyHasLotsOfSex screwing around]] going on there.
