I do want to mention that the Internet Archive was hacked precisely in the middle of my research (alongside a friend) into Lux Madriana's activities in the late 1970s. Suffice to say, it was unfortunate timing and quite a shock to our systems, a reminder of the realities of a digital lifestyle, I suppose.
I want to clarify that I'm still not clear on who hacked it or why, so I cannot comment on that, except to say that I want it back ASAP.
