The Ludlow-Santo Domingo Library is the world’s largest private collection of material on altered states of mind. The 50,000-plus-item collection documents psychoactive drugs and their physical and social effects. It covers everything from cultivation and synthesis to the myriad cultural and countercultural products such altered states of mind have inspired and influenced.
There are also approximately 2,000 film posters and stills, largely documenting drug-related films and psychedelic “happenings.”
