Four-fifths of 913 public and private colleges and universities recently surveyed were either in a fundraising campaign or about to enter one, according to Linda Durant, vice president of development for the Council for Advancement and Support of Education. More than 50 campuses have launched $1-billion fundraising campaigns. Fourteen have aimed even higher, at $5 billion or more, including five public institutions: UCLA, UC San Francisco, University of Washington, University of Virginia and University of Michigan. USC raised $7 billion in its recent campaign.
