The butterfly effect explains change. The Berkeley Effect changes the world. The Library Effect changes the way you see the world. If a butterfly flapping its wings in Brazil can cause a tornado in Texas, then surely the generous hearts, good deeds, and great leaps of UC Berkeley can spark positive change all over the globe. On Thursday, November 17, you can be that change by helping the University Library make the world a better place during Big Give — our third annual online fundraising blitz.
