Dr. Dean Radin has created a new page with links to papers providing some of the best evidence for the existence (and form) of psi (psychic phenomena and abilities). From the list, one can download the papers for free.
These are “Selected Peer-Reviewed Journal Publications on Psi Research.”
Also on the page are links to websites with access to additional papers, and a list of recent books recommended to get one “up to speed” on Psi Research.
According to Radin, there will be additional papers added as time goes on, so check back often.
