    • 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?
