Ah, so -
Unfortunately, it appears you are correct. The first time I went to the Archive.Org site, it appeared to have your entire collection available and I was able to browse through a lot of my favorites, including your great series from South America; this time hardly anything. Maybe it depends on which archive date is selected, and on at least one occasion your entire site got saved. I'll do some more exploring and ex-Sperry-menting later
