Hey Man, thanks for the offer! (that's a pun).
Another member of tclug was kind enough to send me the Beginner's Guide. 
The other one that would download only some kind of 13K preamble was 
"Plant Anatomy," but that one is huge (about 150 MB according to the 
first good Samaritan). If anyone has something like Google Drive that 
they could upload it to, I would be grateful for a shareable link. 
Otherwise, I could get along without it. I did download one at a time 
about 50 others.
Now I would like to know why this glitch cropped up but I am not likely 
to figure it out. I am only an occasional user of linux (mint 19) and I 
know almost nothing about python.

Thanks,

Ed
