  1. NLM Webinar: 2023 MeSH Highlights

  2. NLM Office Hours Special Listening Session: MeSH

    Following our first NLM Office Hours Special Listening Session in June 2022, this event will continue the conversation on how NLM and our users can work together to update the MeSH vocabulary.

    Dianne Babski, NLM Associate Director for Library Operations and Dan Cho, Technical Information Specialist, NLM MeSH Team, will briefly discuss how NLM determines which new and updated terms are added to MeSH and share factors that impact the updates to MeSH.

    The remainder of the session will be reserved for attendees to share their feedback and ideas on future improvements to MeSH. Statements can be focused on these general categories:
    • What other feedback do you have about MeSH?
    • What should we consider reviewing? Why?

    We invite you to share feedback in advance by emailing with the subject line "MeSH Listening Session." Please include in the message your name and which pronouns we should use to refer to you when sharing your feedback during the session.

    A recording of the Listening Session will be made available following the event, along with a document summarizing feedback received before, during, and after the Listening Session.

    Date and time: Wednesday, January 18, 2023, 2:00 p.m. - 3:00 p.m. EST

  3. NNLM Class: MeSH Changes and PubMed Searching

    When MeSH is updated each year, your PubMed searches may be affected. Join us for "MeSH Changes and PubMed Searching" to learn:
    • How do MeSH changes affect your PubMed searches?
    • What happens when a term gets changed, added, or removed; or moved to a different part of the MeSH hierarchy?
    • How do you accommodate vocabulary changes over time in your comprehensive searches?
    • How do you check your saved searches and alerts?

    Date and time: Friday, January 27, 2023, 1:00 p.m. - 2:30 p.m. EST
