2022 Ovid MEDLINE® Reload News

The Ovid MEDLINE® has been reloaded to implement the 2022 MeSH.

In addition, Ovid has made the following changes to the database:

Changed Field

Label   Field Name   What's Changed
SB   Journal Subset  

The NLM has discontinued their Journal Subset (SB) limits for MEDLINE/PubMed with the 2022 reload, with the exception of "index medicus.sb." and "oldmedline citations.sb.". All other ".sb" searches will stop functioning after the reload, as the NLM has removed all other SB indexing from the database. We strongly recommend that you review your search strategies if you used the Journal Subset (SB) field.

 

Changed Limit

Limit Name   What's Changed
Journal Subset  

The Journals Subset limit is also affected by the above mentioned change. However for the Journals Subset limits Ovid does have the ability to replace them and ensure existing Ovid search strategies and alerts don't break when they use any of these limits. The new limits are based on NLM Catalog searches using matching MeSH terms and title words for these subject areas. Please note the new limits and the ensuing results don't compare to the old NLM versions, so we strongly recommend that you review your search strategies if you used the Journal Subset limits.
