The undergraduate library is defined as a library unit, separately housed with services geared at the lower division undergraduate student on a university campus. Using this definition, there are ten undergraduate libraries in the United States: (1) Harvard University, (2) University of Michigan, (3) University of South Carolina, (4) Indiana University, (5) Cornell University, (6) University of Texas, (7) University of Illinois, (8) Stanford University, (9) University of North Carolina and (10) University of Nebraska. Each of these is an undergraduate library, yet each is different in areas ranging from the computerized complexities at Stanford to the elegant simplicity at South Carolina. Six basic ways the undergraduate library differs from the traditional university library are: (1) provides open access to the collection, (2) centralizes and simplifies services to the undergraduate, (3) provides selected books of value for liberal education as well as the reserved book collection, (4) attempts to make the library a tool for instruction in library use, (5) provides services additional to those given by the research collection and (6) constructs a building with the undergraduate's habits of use in mind. Each of the ten undergraduate libraries was discussed during the institute. (NH)
