At the beginning of the twentieth century, many Iowa communities secured funding from Andrew Carnegie and the Carnegie Corporation to build public libraries—101 in all. Additionally, Carnegie provided funding to build seven academic libraries in Iowa. The Carnegie Libraries in Iowa Project (CLIP), a partnership between the University of Iowa's School of Library and Information Science and Iowa's librarians, is charting the history of Iowa's Carnegie libraries through photographs, architectural drawings, and statistical data. The collection is intended to be a starting point for any researcher interested in the social, historical, and architectural history of Iowa libraries.
