To resurrect an old thread, just cuz it's pertinent to my question: In late 2000, I downloaded 3 Luther works for my Palm. I may or may not have gotten them from Project Wittenberg.
These are in DRM-free PalmDOC format, which the wiki says is translatable by mobi2html (or perhaps mobi2mobi, since mobi is what I want as an outcome). My installation of MobiPerl isn't cooperating right now. Anybody want to re-format these and add to your own upload count? I'm looking for a mobi version!
