The above quote is from Enough About You by David Shields ’78. The library he closed “every night for four years” was the Rockefeller Library. Here is the full paragraph from Enough About You:

During freshman orientation, I joined the Brown Daily Herald, but by February I’d quit — or perhaps I was fired — when there was a big brouhaha surrounding the fact that I’d made stuff up. I started spending long hours in the Marxist bookstore just off campus, reading and eating my lunch bought at McDonald’s; I loved slurping coffee milkshakes while reading and rereading Sartre’s The Words. I closed the library nearly every night for four years; at the end of one particularly productive work session, I actually scratched into the concrete wall above my carrel, “I shall dethrone Shakespeare.”
