There will still be more books than you could ever read, but visitors to this week's Frankfurt Book Fair will also be invited to don virtual-reality goggles, visit an interactive classroom and discover 3-D printed art as publishers plug into new technology.

Organizers of the world's largest publishing event say the focus on art and technology is a logical next step as the creative industries become ever more connected.

The fair, which opens on Wednesday and is expected to draw some 275,000 visitors, has always been about "content-regardless of its format", the event's vice-president Holger Volland says.
