Heartening statistics on reading in the US

This is an article from a few years ago that shows that Americans seem to be reading more books, not less.  An increasing share of that reading comes via electronic devices, but there is still a lot of reading of physical books, too.  Other interesting stats--blacks as a demographic group seem to have higher rates of readership than whites or Latinos, Latinos own tablets at higher rates, and rural people read at higher rates than suburbanites.
