In December 2016, the National Library of Medicine established the MeSH (Medical Subject Heading) Indexing Assessment Project to evaluate the impact on users of assigning MeSH terms to MEDLINE citations. The project findings confirmed the value of MEDLINE indexing and the value of applying selected non-subject metadata to MEDLINE citations. In response to the findings and as part of its Strategic Plan, NLM created the five-year development plan, MEDLINE 2022. A Working Group, comprised of members from across all NLM departments, was charged with the plan’s implementation.
MEDLINE 2022 has eight specific goals describing challenges that must be addressed to maintain the usefulness of MEDLINE as a tool for discovering and analyzing the biomedical research literature:
The goals of MEDLINE 2022 align with the goals of the NLM Strategic Plan, most importantly Goal 1: Accelerate discovery and advance health by providing the tools for data-driven research. MEDLINE has provided access to the biomedical literature for more than 45 years, evolving as publishing and information retrieval have evolved. The MEDLINE 2022 project aims to ensure that MEDLINE continues to evolve to meet the needs of users in an age of data-driven discovery. NLM will keep its many stakeholders informed of progress with the implementation of MEDLINE 2022 by publishing future NLM Technical Bulletin articles with details about different aspects of this project.
