Since 1984, approximately 83,700 citations for State-produced agricultural publications have been added to NAL's AGRICOLA database as a result of cooperation between land-grant universities and NAL under the NAL/Land-Grant University State Agricultural Publications Program.
The National Agricultural Cooperative Cataloging (AGX) Program consists of a network of libraries that prepare machine-readable cataloging for agricultural titles. The program has seen significant growth in recent years. In 1990, the program's scope was expanded to include citations for agricultural theses and dissertations. In 1991, Colorado State University, Louisiana State University, and the Universities of Maine, Maryland, Minnesota, and New Hampshire joined the University of Florida, the University of Nebraska, and the Massachusetts Institute of Technology in contributing citations of current research materials.
In 1992, the University of Arkansas and the University of Kentucky became participants. In 1993, Ohio State and Texas A&M Universities renewed their participation in the Cooperative Cataloging Program, and the University of Nevada and Virginia Polytechnic Institute and State University began contributing records. Discussion began in 1993 to bring Kansas State University (KSU) into the AGX program as part of the KSU/NAL demonstration project, whose mission is to establish standard practices for providing current and long-term access to educational materials in all media. As part of this project, in 1994 KSU began contributing agricultural titles to AGRICOLA.
