I suspect this is a few years before 1960, when I arrived at Uni, but the Library is as it was then. To the right were the book stacks, remarkable for their glass floors. That door at the end opened on to a small balcony. At desperate times, as when essays were due, some students used to take books out there and throw them down to waiting accomplices. Needless to say, I didn’t. 😉 The area is now known as the McLaurin Hall.
