I just came across this photo essay, which makes me retroactively pissy about the ugliness of the library at the university (style: Cinderblock Brutalism) where I took my undergrad degree. Though to its credit, it had the most napworthy armchairs I've ever encountered. People used to race -- RACE, I tell you -- to nab a chair before 1:30 pm. It was unseemly. And if you got there too late, you were forced to wander around forlornly, envying all the snoring droolers.
I've been making myself feel better by noting that I can't spot any good nap spots in these photos.
