Articles referencing this book. The Cottingley Fairies Society for Psychical Research Spiritualism

This encyclopedia is specialized around people and subjects concerning spiritualism, ESP, ghosts, and altered states... and it's a good reference manual for these subjects. Each article will give you the important names, places, and dates regarding any particular phenomena; but don't treat this as the last word on these subjects. Despite it's overall usefulness as a starting place, it's just a starting place; there are some minor factual errors, so, as always, double-check before you take an article at face value.
