KBART stands for Knowledge Bases and Related Tools. It is an industry standard for recording electronic resource holdings so providers of electronic resources and knowledge bases can communicate and create accurate links in Discovery Systems and other OpenURL environments. You can download a KBART file of holdings from the vendor's admin site or from Collection Manager, make modifications to represent your holdings, and upload the new information to Collection Manager.
