Updates on PubMed and NLM Catalog Filters and Subsets. NLM Tech Bull. 2021 Sep-Oct;(442):e8.
In April, the National Library of Medicine (NLM) announced an Update on PubMed Specialized Search Queries: Selected Queries No Longer Updated; Remain Available for Download and Customization.
The last version of the selected PubMed Special Queries are available to use as a base to customize, update, and save as your own search strategies in My NCBI. To create your own search strategies, visit Saving and Managing Searches. There is also information and instructions on using MeSH and searching PubMed more effectively.
Several of these specialized queries were available in the PubMed filters sidebar using the "Additional filters" button. These queries have been removed from the filter sidebar options in PubMed (see Figure 1).
The SUBJECT category and associated filters have been removed from the PubMed interface:
The following filters from the JOURNAL category have been removed from the PubMed interface:
The Systematic Reviews filter is still available as a default--always visible--filter under the ARTICLE TYPE filter category.
In early December, the associated filters and subsets will be removed from the PubMed and NLM Catalog indexes during NLM’s Annual MEDLINE/PubMed Year-End-Processing activities.
After the Year-End-Processing update, these filters and subsets will no longer work when searched in PubMed or NLM Catalog as part of a query, such as: aids[sb], or jsubsetn.
Additionally, the PubMed EFetch, FTP baseline and update XML files will no longer carry these subset values, e.g., <CitationSubset>AIM</CitationSubset>.
