This is a great topic. As it's sort of a fork in the thread from the main point of the conversion tutorial and alternate conversion methods, I've created another thread
for the portion of discussion related to sharing and making available the best converted public domain documents for e-book readers. Please feel free to join in the conversation and add your thoughts.
With respect to this ongoing thread, I'd like also if someone can find and share a link to that follow-up article that Branko mentioned with more information about conversions. Or is it written, but not yet published?
At any rate, let's continue the discussion about conversions here, but please make the jump
to talk about how the converted documents might best be hosted and indexed.
