Starting in 2017, the NLM Classification, available online at https://www.nlm.nih.gov/class, has moved from an annual spring update to twice-yearly updates. The 2018 winter edition has been issued as of January 31, 2018.
For the winter edition, the 2018 MeSH (Medical Subject Headings) vocabulary was evaluated for inclusion in the Classification index. Several additions and changes were made to the Index and Schedules based on this review. All main index headings are now linked to the 2018 vocabulary in the MeSH Browser. Additional minor updates were made to the Index and Schedules.
