This biographical dictionary contains profiles of 330 psychics worldwide from Tony Agpaoa to Elenor Zugun, each accompanied by a bibliography listing the primary sources consulted. The primary focus is on those claimed psychics who have figured prominently in the history of the subject, though some lesser-known figures are included to show how rich, varied, and colorful that history has been. The aim throughout is to present each case as fairly and dispassionately as the facts allow, with a particular eye for accuracy in details and presentation. The approach is historical, not apologetic or accusatory, making the work ideally suited as a permanent reference.
