Updates on PubMed and NLM Catalog Filters and Subsets

​In April, NLM announced selected queries will no longer be updated. As these queries are no longer updated, the associated filters were removed from PubMed. In early December, the associated filters and subsets will be removed from the PubMed and NLM Catalog indexes during NLM’s activities. Aft er 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.
