At least three of those stores, 1 the company's 330,000-square foot headquarters, were in my backyard (Ann Arbor, Michigan). Borders' departure left us with a handful of secondhand booksellers, one 2 independent and a single Barnes & Noble. The sense that we'd gone from feast to 3 overnight was indelible, a sense driven by presumptions that physical books are doomed, to be assimilated by the Borg-like inexorability (无情，冷酷) of the digital medium. If you hold with some of the less 4 analyst predictions, the writing may even be on the wall for the company Barnes, Noble and eventually Leonard Riggio built. Each year the Publishers' Association rolls out a bunch of numbers canvassing (调查意见) the last year's book sales. 5 what we think we know about physical books, this year's numbers are something of a surprise. For starters, book sales overall—that is, both digital and physical formats—actually 6 4% in 2012 (over $5 million). That's a record, made even sweeter because 2011 revenue had been 7 —a 2% slump from 2010. We can thank digital for much of the 8 , of course, with overall digital sales up a whopping (巨大的) 66%, sprit between e-book sales (up 134%) and digital fiction sales (up 149%). And yes, physical book sales were 9 though with a mere 1% dip, only slightly. But what I'm not sure anyone was expecting was this: Total sales of physical books in the fiction genre actually grew by 3%. Take a bow, Fifty Shades of Grey. Another area physical book sales grew: children's books. Why? Well, the rate at which readers are shifting from physical to digital books appears to be related to what each genre tends to do best or uniquely: PA reports 26% of fiction sales were digital, but that figure drops 10 5% for nonfiction and just 3% for children's books.
