Baltimore, MD - January 12, 2021 - The National Information Standards Organization (NISO) is pleased to announce that four more publishers have recently started supplying metadata that conforms to the NISO recommended practice, KBART: Knowledge Bases And Related Tools (NISO RP-9-2014). A total of 62 publishers have now achieved KBART compliance since the recommended practice was originally published in 2010. An estimated 40% of full text usage on publisher sites is driven by library databases (including Google Scholar and Next Generation Discovery Tools). Much of this access flows through OpenURL link resolvers that rely on detailed knowledge base title data provided by publishers and other content providers, making accurate, up-to-date information essential to maximize usage. By adopting the universally-accepted KBART metadata structure, publishers ensure a timely exchange of standardized information and updated product availability details across the whole supply chain.
