I was on the phone with Doug doing score corrections when there was a big crash behind me. I turned around and a shelf of books was all over the floor. I blamed Annabelle, and then Jen called me from the fifth floor to ask if I felt the building shaking. I didn't, and she said, I think we had an earthquake. I went back to work with Doug, and he had top leave by 10:30. So I cleaned up the books abd put them away.
