From the April 3, 1999 entry at http://www.maydaymystery.org/mayday/update.html :

This week sucked, so nothing really got updated, but I took a cue from one of the previous emails and decided to blow off about 3,000 important things I should have been doing and read Magus (link to Amazon product page) instead.

I have my complaints about Amazon, but you know what I respect the hell out of them for: that 27-year-old web link still works.
