At the University of New Mexico's Engineering Library (Big main library also has these) they have these little alcoves with closed, locking doors that grad students use to write/read their thesis and so on; can't be bigger than 5x10 feet. They're hard to get and always in high demand. When I was an undergrad I wanted one but of course they weren't allowed for undergrads.
