TL;DR

This is a reference book, not an argument. Jerome Clark, a longtime UFO historian and editor of the International UFO Reporter, assembles an alphabetical encyclopedia of the entities that populate contactee lore, abduction accounts, and older folklore. Each entry lays out who reported the being, when, and where the story came from. Read it as a well-built map of what people have claimed, with sources you can chase, rather than as evidence any of these beings exist. On that narrow but honest job it succeeds cleanly.

What it claims

The book does not claim the entities are real. It claims to record them faithfully. Entries run from George Adamski’s benevolent Venusians and the “space brothers” of the 1950s contactee scene to fairies, angels, and other otherworldly intelligences drawn from centuries of folklore. Clark treats these as cultural artifacts worth documenting, tracing each account to its origin and noting where a story was exposed, revised, or abandoned. The organizing thesis is quiet: the modern alien is one chapter in a much older human catalogue of encounters with the more-than-human.

Why it matters

Most UFO writing either believes too much or sneers too early. A neutral reference that simply pins down who said what, and when, is rarer than it should be. Clark’s book gives researchers a shared, sourced baseline for the contactee era and its stranger fringes, which is exactly the kind of groundwork our ranked cases depend on. It also quietly makes an argument by arrangement: put the space brothers next to the fairies and the family resemblance is hard to unsee.

Does it hold up?

Yes, on its own terms, because those terms are modest. This is reference work, so the right test is accuracy and sourcing, and Clark scores well on both. He documents claims, attributes them, and separates the account from any judgment about its truth. That method ages far better than the credulous contactee books it describes. The obvious caveat is one the book itself never hides: cataloguing a claim carefully is not the same as showing the claim is real. Nearly everything inside rests on personal testimony, some of it from figures later caught fabricating. Trust the book as a guide to the literature. Do not read a well-written entry as confirmation the entity was ever there.

Read this if

You want a sober, sourced field guide to the entities behind the encounters, useful for tracing where a story started rather than deciding whether it happened.
