I'm trying to write a potted history of this infamous book to add to an online ebook edition I'm creating (with added notes and detailed credits).
I've got most of my information from old magazines available in Ask Alexander, so have most of the pertinent details. However, in his excellent blog post on the book, David Britland says the following:
The last secret that the Encyclopedia had to offer was only revealed to me recently on browsing through some old copies of Genii magazine. In the February 1969 issue Glenn Gravatt confessed that his co-author was entirely fictitious.
Now, I've read that entire issue and I cannot find the confession by Gravatt. Is it published elsewhere? If so, does anyone on here know where?
