The Wikimania conference is taking place in London this week, attracting Wikipedia fanatics from around the world.

One publishing firm has ambitious plans to print the online encyclopaedia as a vast collection of physical books, to show how huge it has become.

Pedia Press has a partnership agreement with the Wikimedia Foundation, and already offers a facility to print certain articles from the encyclopaedia.

Originally Pedia Press tried to raise money through crowdfunding for the project, though now it is turning to private investors.

Christoph Kepper of Pedia Press spoke to BBC News by online video call from Germany, to explain the motivations that lie behind the project.
