Che's Bolivia Diary
Original scans of Che's handwritten diary are now available on chebolivia.org. Apparently the Cuban publication of his dairy was cleaned up. Here, you can see what he really said.
One of the files is a PDF which includes printed text along with the original scans. The hand-written stuff is pretty hard to read so this seems to be the best choice. When I was trying to download it the site was having problems so, once I got a copy I put it up on A42. You can download it from there if you have problems with the original site.
Now I will wait for comments from our Che. :-)
