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.
We would like to remind all customers that database listings on Ovid are fully customizable. There are over 40 combinations of Ovid MEDLINE available for display in the database list. However we strongly recommend to keep things simple for your users, and only show the all-encompassing “Ovid MEDLINE(R) ALL <1946 to Present>” (MEDALL), which is our PubMed equivalent in terms of coverage.
Please note, we will provide all Ovid MEDLINE customers with a complete overview of all available segments in the 2021 reload in a follow-up communication, prior to the reload.
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].
