High Weirdness By Mail – A Directory of the Fringe: Crackpots, Kooks & True Visionaries, by Ivan Stang (ISBN 0-671-64260-X) is a 1988 book dedicated to an examination of "weird culture" by actually putting the reader in touch with it by mail.
The book is divided into sections—"Weird Science," "UFO Contactees," "Drug Stuff," and others, and each section contains a variety of mini-articles describing organizations.
Each organization article concludes with a mailing address (and in some cases, phone numbers), with many entries referencing publications and (in some case) merchandise that at the time of the book's publication could be requested free of charge or for the cost of postage.
Stang reported this incident to the FBI, but did not receive any actual harassment or threats from the groups in question.
Stang on cassette entitled High Weirdness by Mail, recorded live at the 1993 WinterStar Symposium.
