One word..........

There is a hard core of dedicated readers (I count myself among them) but book readership has declined over the last few decades.

Here's an article from Atlantic about it:

And hard date from a recent Pew Research study:

While most people still read books, they read fewer than in earlier decades, and some use e-readers in place of hard copies (I find e-readers impossible to read for long stretches, so I only use mine for travelling and some research-type volumes).

I kept a book list for many years, and while I averaged over 200 books annually(mostly fairly heavy-duty nonfiction), in the last decade it has dropped to more like 75 as I do read online, but mostly magazines, professional journals and news items.

There's danger, however, that too much online reading can adversely affect our ability to sustain attention and comprehension to difficult text. Here's a Huffington Post article about that:

While the book referred to is a popular science work, serious cognitive science scholars are finding similar results, see for instance the work of Maryanne Wolf from Yale.

I invested in a Nook a year ago. Since then, I've read five Heinlein novels, two by Poul Anderson, one by Twain, the first five Ian Fleming Bond novels, Levon Helm's autobiography, and am now working my way through the Jack Ryan books in chronological order (almost done with Cardinal of the Kremlin). I left out a half-dozen or so works on non-fiction.

The Nook (the basic black and white one with backlight, which runs for weeks on a charge) has taken a steady reader and turned him into an obsessive one. :-)

That being said, I need to track down Turing's bio.
