With Wikipedia blacked out for 24 hours in protest of a pair of anti-piracy bills under review in the U.S. Congress, students scrambling to write early-semester research papers without the open-source encyclopedia posted panicked remarks to Twitter. And just as fast as the 18-22-year-old cohort tweeted about their plight, 30-somethings nostalgic for late nights spent poring over Encyclopedia Britannica sent snarky retorts. But at dozens of universities, students received supportive tweets from a place where Wikipedia is often a dirty word: the library. “No Wikipedia, No fears.... The library is always here with all the answers you will ever need!” tweeted the staff at Temple University.
