New eBook Formats Available!

I've been going back and optimizing some of the existing eBooks on the blog, using some new tools to clean up the code and making more device-specific versions, with hopefully better functioning table of contents (TOC).  All new ebooks added to the blog will feature Sony (epub), Nook (epub), Kindle (mobi) and PDF versions.  As time permits, I'll be updating some of the older ebook entries.
