(Knowledge Bases and Related Tools) is an industry standard used by Knowledge Bases and Libraries to find out what eBook and Journal content they licensed and how to link to it. This is an integral part of the Discovery layer. With KBART a library's Discovery Service knows which books and journals a library has access to from a publisher. This allows the library's users to search the content the library purchased and when found click through to the content hosted on the publisher's platform. We provide (per the ), KBART lists for each package we license, and for consortia licenses, so customers can select their licensed content in their Discovery Service.
