Agriculture Network Information Center: The Agriculture Network Information Collaborative (AgNIC) alliance was formed in 1995 by a group of four land grant institutions - Cornell University, Iowa State University, University of Arizona, and University of Nebraska-Lincoln, and the U.S. Department of Agriculture's National Agricultural Library (NAL).  In 1998, NAL assumed the role as “secretariat” to move the partnership forward.  Members were committed to creating a voluntary “alliance” dedicated to providing Internet access to quality, authoritative agricultural information, and specialized reference services.  In 2007, with 60 voluntary partners, this vision continues to sustain the Alliance, largely due to its collaborative nature.  University libraries affiliated with land-grant colleges—as well as other interested institutions, such as the International Rice Research Institute, the American Farmland Trust, the Agricultural Information and Documentation Service for America (SIDALC) and the University of Buenos Aires, School of Agriculture, Central Library, are working together with NAL to develop the AgNIC Alliance, its collections and services, and the technologies upon which it relies.

Agricultural Development in the American Pacific: The Agricultural Development in the American Pacific (ADAP) Project was formally organized by the five directors of the Land Grant institutions in Hawaii and the United States-affiliated Pacific Islands (USAPI) in 1988, with the deans/directors of the Land Grant institutions serving as the Board of Directors.  The purpose of ADAP is to strengthen existing Land Grant programs by sharing and focusing resources on priority areas of common concern and interest.  Priority areas are often unique to the Pacific region, having to do with tropical/subtropical island agriculture and cultural practices.  Due to the unique natural and human resource base of the Pacific island agro-ecosystems, it is often not possible or appropriate to transfer results from temperate zone agricultural research, and materials for extension and teaching used by continental US Land Grant programs.  ADAP supports applied research within the region, and the development of effective extension materials that are culturally appropriate.
