I forgot to mention that I recently posted another public-domain text over at the Monadnock Press: Henry David Thoreau's essay Walking. I'm also slowly converting all of the Monadnock Press texts (and the books I've written) over to fully conformant XHTML 1.1 as the first step toward producing ebook versions for Kindle, Nook, etc. All in my copious spare time, naturally. :)
