brown wooden mini stair in between of book shelves

I had a few hours to kill in Copenhagen, so I went to the Sorte Diamant Library to take some photos. Libraries are quiet places and staff members aren’t always thrilled to hear camera shutters go off. As I was firing away, I noticed a staffer approaching from my side. I said a photographers’ prayer and prepared to get told off. He said to follow him and I obliged. We walked through a door with a “staff only” sign, found our way down a narrow corridor and entered a huge room, dimly lit, filled with archived books. “You’ll get good shots in here”, the librarian said and then got back to work.
