I was sitting at a university library  in a small, white cubicle a few years ago. Those cubicles were just big enough for one person to sit in with a ledge that served as a table and a shelf above the ledge that held books. Under the table-like shelf were plug points for laptops. These cubbyholes were highly prized and had to be applied for way in advance. Only very few people ever got one allotted to them. The tops of the cubicles were open and there were locks on every door. The keys were the coveted prize.
