The Library

"It's a world. Literally; a world. The whole core of the planet is the index computer; biggest hard-drive ever, and up here, every book ever written. Whole continents of Jeffrey Archer, Bridget Jones, Monty Python's Big Red Book. Brand new editions, specially printed."

- The Doctor.

The Library was a huge library that was built during the 50th century. It contained every book ever written and spanned a whole planet, within its core was the largest hard drive ever, serving as an index computer. The planet has one moon; Doctor Moon.

It was commissioned by Felman Lux and was managed by a head librarian. The computer interface was mainly based on courtesy nodes; sculpture-like info terminals containing real faces made from donated flesh. It also contained levitating spherical wooden security cameras. Visitors were advised to switch off their mobile comm units.

Paper editions of every book ever written were made specially for the Library, but unfortunately the forests cut down to make the books were home to Vashta Nerada, who then hatched from the books and infested the library. The computer managed to "save" all 4022 visitors to its hard drive, where they could dream an imperfect virtual existence. The computer sealed off the planet, and it would be 100 years before the Lux family would arrange an archeological expedition led by Professor River Song to find out what happened.
