I could swear there is a free kindle version someplace, but I can't find the source at the moment. ETA: I was thinking of one of his other books "Thinking as a Science" which is available from archive.org - http://www.archive.org/details/thinkingasascie00hazlgoog
I have something (http://boxerbiography.blogspot.com/) I want to convert to either Mobi or just a single page. I was thinking of writing a ruby script to do it, but if there is an easier way, would love to know.
TBH, I had this one lying around from a torrent I obtained someplace a while back.
In general though, Calibre can handle conversion between various formats (http://calibre-ebook.com/) - I use it to convert the odd HTML ebook to MOBI for my Kindle with reasonably good results.
