Update: PubMed Baseline Release Scheduled for January 2025. NLM Tech Bull. 2024 Nov-Dec;(461):b17.

The release of updated MEDLINE citations with 2025 MeSH is scheduled for early January 2025.

The National Library of Medicine (NLM) expects to temporarily suspend the addition of fully indexed MEDLINE citations to PubMed the week of January 6, 2025. NLM will continue to add publisher-supplied and in-process citations during this time.

The new PubMed baseline files are expected to be released the week of January 6, 2025. Daily update files will continue to be added to the FTP until the new baseline is released.

More information about MeSH 2025 updates is available: Annual MeSH Processing for 2025. Please contact the NLM Help Desk with any questions about year-end updates to MEDLINE data in PubMed.
