The Observer's Robert McCrum commented on the changes he's seen in publishing. As an overview, the article states:
"This is a story whose outcome remains mysterious. There's no doubt that this transitional decade from the 20th to the 21st century has been decisive, but no one knows when or how it will end. One thing is certain: the appetite for print is growing. In 1996, there were between 60,000 and 100,000 new titles in the UK each year. By 2007, it was pushing 200,000. That's the biggest annual output of any country in the Western world, turning over some £4 a year."
The article covers books beyond the business genre, but it's interesting to read the insight of someone who's been in the game as long as McCrum. What's underplayed is the larger impact of digital, why and how it can be important, and what's coming.
