Whatever the real number clearly Amazon remains the leading
ebook vendor and its continuing refusal to support library lending locks libraries
out of the most
popular format from the vendor with the best title selection and the lowest prices.
eBooks.com is one of the most
popular digital book stores around, who have a huge range of
ebooks available in many different
ebook formats, including EPUB, and with great iPad and Android apps available, they are well worth checking
out.
