Borders had an estimated 8.1% of retail sales of new printed books in 2010, compared to 22.5% for Amazon.com Inc., and 17.3% for Barnes & Noble, according to estimates from the Institute for Publishing Research, run by Fordham University Prof. Albert N. Greco.

What go my attention in the section above is that Barnes and Noble is only 5.2% behind Amazon.com in market share for new printed books. Would have thought Amazon would have 30-40% market share and hacve a significant lead over other retailers.
