Moving an archive is always a major undertaking. BBC News has an article and an excellent video describing the process of moving the British Newspaper Library from its old home in Colindale in north London to Boston Spa, Yorkshire. The reason for the move is simple: the old location has run out of space.
This project involves six floors of a building with 50 kilometres of shelving. To add even more complexity, the newspapers are stored in a low temperature, low humidity, and low oxygen environment designed to prevent fire and preserve the life of the collection.
The movement of all these newspapers and other documents will require more than six months to complete. You can read the story at http://www.bbc.co.uk/news/magazine-25041871.
My thanks to newsletter reader John Rees for telling me about this story.
