Leonora Piper (Psi Encyclopedia)

This is not a separate work: it is the Society for Psychical Research's own Psi Encyclopedia entry on Leonora Piper, one article inside the same continuously maintained online reference this atlas also records as a general source. It descends from that encyclopedia rather than standing beside it, so citing this entry alongside the general Psi Encyclopedia record, or alongside another of its articles, is one editorial voice, not corroboration. Its real limit is the encyclopedia's own limit: an advocacy-adjacent field reference rather than a religiously neutral academic body. Use it for what this specific entry states about Leonora Piper's documented mediumship and the investigations of her; a claim needing independent scholarly assessment of those investigations needs a source produced outside the Society.
