You may have heard the news that Wikipedia (in English) is staging a global blackout in protest of two bills before the U.S. Congress:
You can read a blog about this, “Wikipedia to go dark on Wednesday to protest bills on web piracy,” on the New York Times web site, dated Jan. 16. You also can read Wikipedia’s announcement of the “English Wikipedia anti-SOPA blackout” decision.
The 24-hour blackout will start at 05:00 UTC on Wednesday, January 18, 2012.
If you need encyclopedic information on a topic during the blackout, Andersen Library has lots of encyclopedias (some are even online). Ask a librarian for assistance.
