Let me quote from the "About" page: > HOW’S THIS DIFFERENT FROM PROJECT GUTENBERG OR OTHER FREE EBOOK SITES? > While there are plenty of places where you can download free and accurately-transcribed public domain ebooks, we feel the quality of those ebooks can often be greatly improved. > For example, Project Gutenberg, a major producer of public-domain ebooks, hosts epub and Kindle files that sometimes lack basic typographic necessities like curly quotes; some of those ebooks are automatically generated and can’t take full advantage of modern ereader technology like popup footnotes or popup tables of contents; they sometimes lack niceties like cover images and title pages; and the quality of individual ebook productions varies greatly. Not sure about the Calibre conversion. I normally convert EPUBs to MOBI using Calibre (and switching to left aligned, right ragged), but on StandardEbooks I've been downloading the AZW3.
