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.

quote: My basic
production charges include a PDF for a print version and three
ebook formats: a downloadable PDF, a reflowable ePUB, and a Kindle version.
