After lunch today, I took a stroll through the library. I had admired it from the outside but a librarian who noticed my conference bag while at a coffee shop urged me to visit the inside. Who am I to argue the personal invitation of a librarian? She mentioned the fourth floor was covered in red lacquer and had no right angles. Sure enough, I found the inviting red stairs. There were just meeting rooms there but it felt like I was walking through the heart of the library. It was well worth exploring.
