Ovid MEDLINE 2021 Reload Update
Dear Ovid MEDLINE Customer:
Further to our message on 4 December 2020, we confirm Ovid MEDLINE is being reloaded to implement 2021 MeSH. We expect the reload to go live on February 22nd, 2021. AutoAlerts will run on Saturday, February 20th, 2021 prior to the reload going live.
You can find more information about the changes to MEDLINE and the 2021 MeSH on this NLM page: https://www.nlm.nih.gov/pubs/techbull/nd20/nd20_medline_data_changes_2021.html
In addition, Ovid will make the following changes to Ovid MEDLINE:
Your database resources display for Ovid MEDLINE segments may be affected by the changes above. The MEDLINE Corrections segments (MEDC, MEDCM), if you had them listed, will disappear. Databases labelled “Without Revisions” will lose that label, and a new PubMed-Not-MEDLINE segment (PMNMZ) will now be available for display on request.
Finally we are pleased to let you know we updated the Special Ovid Filter Limit for Covid-19 in December 2020. We will provide the next update for this filter after the 2021 Ovid MEDLINE reload in February. While updating this filter, we have made sure not to “lose” any records from the previous version of the hedge. As before, the full search syntax and search line comments are documented in the Limits section of the Ovid MEDLINE database guide.
Feel free to contact Customer Support with any questions by sending an email to [email protected].
