How many librarians does it take to change a lightbulb?

In this case, none. We had to call in the scaffolders! This light fitting hangs above the stairwell, and changing the bulbs without scaffolding would mean risking your life hanging off a stepladder above a very long drop. Why is the light fitting there in the first place? Who knows, but it was certainly designed in the days before health and safety. Moving it doesn't seem to be an option. Lets hope the new bulbs are very long lasting...

Many librarians here in Cambridge are blessed (or cursed!) with working in very old or architecturally unique buildings. I feel that it's a privilege to work in such an environment, but it can certainly give rise to some extraordinary situations!
