I was quite right - parts of the library ceilings are now caving in, no thanks to leaky pipelines....
Oh dear.
First there was a metal bar which crashed near the escalator leading to the library (fortunately no one was ON the escalator at that time; students are now forbidden to use that route, although I saw a few people who wormed their way through this morning...)
Now this.
Ceiling repairs are underway nevertheless.
Makes me wonder what would be next....
I hope no one gets hurt.
