Notice for PubMed saved searches...

My NCBI Saved Searches and RSS feeds that were created using a date selected from the old PubMed® Limits screen should be recreated as these old limits are no longer working. Recreate your searches using date limits from the new Limits screen (and delete the old searches). Searchers are reminded that updates are, by definition, citations for recent publications that are new to PubMed and will not include citations for articles published before September 1997. Therefore, date limits are not recommended for strategies used to create My NCBI updates or RSS feeds.
