Morbid Anatomy is a compendium of posts about medical and death-related art, such as post-mortem photos, anatomical waxes and ecorches [engravings of partly flayed people showing musculature]. Off I go to waste my lunch hour. Janet would definitely have some of this stuff in her lab alongside the Kraftwerk posters.
EDIT: The links from Morbid Anatomy are most instructive and detailed. For example, The Fantastic in Art and Fiction is a bank of thematically grouped images [Madness & Possession, Angels & Demons, the Grotesque] from across the centuries, supplemented with lists of scholarly studies, literary works, plastic arts and movies that pertain to the theme. There are many wonderfully freaky out-of-copyright images here that would be great for indie authors illustrating their own book covers.
