Web 2.0 technologies allow for increased collaboration between agricultural libraries through tools like social networking, blogs, wikis, and video conferencing. Collaboration provides benefits like reduced costs, enhanced services, increased quality and availability of resources, and solving complex problems. Some key collaborative resources for agricultural libraries include institutional repositories, library consortia, and databases like AGRICOLA, AGRIS, and CARIS. Suggestions to improve collaboration include sharing collections, developing common databases, and open communication between collaborative libraries.
