‘And this is why we need Sunday opening too’ said the librarian as she led us through the main reading room of the National Library of Scotland (recently refurbished with lovely new blue chairs).

I glanced over and understood her message when I saw a six foot tall tower of books balancing in the middle of a highly-polished mahogany table. Some poor student was attempting to get through all this material in a single day due to the library’s restricted opening hours.
