Dear Ovid MEDLINE Customer:
We are preparing for the annual global data reload of MEDLINE. As in past years, the National Library of Medicine (NLM) will end their 2021 distribution of updates to make the transition to the 2022 version of MeSH. On December 1, 2021, the NLM expects to temporarily halt the addition of “MEDLINE” status citations, but we will continue to add citations with the status “Publisher” and “In-Process” to Ovid MEDLINE uninterrupted. Once the NLM completes their year-end activities, they will deliver the first new “MEDLINE” status records around mid-December and we will add them to Ovid MEDLINE again.
The Ovid MEDLINE reload with MeSH 2022 is currently scheduled to go live on February 28, 2022.
Important note for users who currently run AutoAlerts for Ovid MEDLINE
While the NLM performs its annual data maintenance, no new fully indexed status MEDLINE records are added and will therefore be missing from AutoAlert results. The NLM expects the normal MEDLINE update schedule to resume mid-December 2021. Ovid AutoAlerts at that time will include new status MEDLINE records added since the previous update. AutoAlerts that include Publisher and In-Process results will run as normal, depending on what the NLM supplies to Ovid during their year-end processing activities.
If you have any questions during this time, please contact us at [email protected]. Please consult our Knowledgebase for answers to frequently asked questions about Ovid MEDLINE and the MEDLINE ALL segment.
Regards,
Wolters Kluwer – Ovid
