Many years ago, I was using typing trainer website that had a handful of public domain books available to train on as part of the end-of-course materials. I thought this was really neat, but I ran out of content pretty quickly and lamented the fact that there was nothing else available. Why couldn't you just choose any of the books that were in the public domain? The framework was already there, surely it wouldn't be difficult to implement? I was perplexed by such an obvious oversight and missed opportunity.

Well, today I stumbled upon the exact thing I had wanted to have back then and just wanted to share.
