Knowledge Base and Related Tools (KBART), initially founded with a focus on improving OpenURL linking through the definition of best practices for exchanging title-level metadata, continues to gain traction and has the potential to be an initiative that improves not only link resolver quality but also improves discovery services, electronic resource management (ERM) systems, and even Counting Online Usage of Networked Electronic Resources (COUNTER) usage reports. In this column we quickly review the history of KBART from its inception in 2007 through the creation of the Phase 1 and Phase 2 best practices. Then we investigate how KBART can positively influence the quality of discovery services, ERM systems, and COUNTER. Finally, we put forward some suggestions on how KBART can become the key to standardizing the exchange of holdings data within the information supply chain to address needs beyond link resolvers and eliminate some redundant holdings maintenance tasks in libraries.
