This report brings together demographic projections, social trends, projected changes in the context of American higher education, and the anticipated needs of an increasingly diverse student population in an effort to offer guidelines for college union and student activity professionals looking to the 21st century. The report contains a reproduction of the charge to the committee authorized to produce this document, an introductory essay, six essays by diverse authors, and a set of recommendations. The first, introductory essay by J. William Johnston, describes the current and expected changes in higher education, the importance of education in current society, and the importance of out-of-class activity in the college experience. The other essays making up the report include the following: "The Changing Educational Environment," by J. Thomas Eakin; "Funding for College Unions and Student Activity Programs," by Robert Lundal and Thomas Levitan; "Student Activities and Programs," by James Osteen and Thomas Levitan; "The College Union of the Future," by Mary Yates and Frank Canavit; "The Arts in the College Union," by Vance G.
