The Bancroft Library, the special collections library at the University of California at Berkeley, has acquired the Michael and Cynthia Horowitz psychedelic archives, a collection that includes the manuscripts of Robert Anton Wilson's Schroedinger's Cat trilogy and the first Cosmic Trigger book, along with materials from Timothy Leary and other authors who wrote about psychedelics. Michael Horowitz was Leary's archivist and his collection of Leary's papers are owned by New York City's public library.
The Horowitz psychedelic archives at the Bancroft Library are listed in the library catalog, but they are still being processed and are not yet available to the public.
There also is a new UC Berkeley Center for the Science of Psychedelics, which has joint programs with Harvard.
