I have proof our house is not the only place that is crammed with a ridiculous amount of books.
I was on the fifth floor of the faculty library. There is not enough room to navigate the shelves. You have to walk in sideways to get at the book. And then you need to bend through your knees and squat in a very inconvenient manner if you want to reach for a book if it is on the bottom shelf.
I had to take a picture and post it here -for added dramatic effect- because no one would believe me if I just mentioned how small it was. The yellow notebook is A5 format. It leaves just a little space left and right of it. A4 fills up the entire space. That's how small it is.
