PubMed Enhancements

At the end of July, the following search capabilities were added to PubMed:

• Stand-alone numbers in both the Title and Abstract fields are indexed in the Text Word field while Title numbers are also indexed in the Title field, e.g.: healthy [ti] AND people [ti] AND 2000 [ti].
  
  
• The Secondary Source ID Field is now indexed as a separate field with the search field tag [SI]. The field is composed of a source followed by a slash followed by an accession number. The indexing is (a) the source, (b) the accession number, and (c) the entire field, e.g.:
  
  genbank [si]
  AF001892 [si]
  genbank/AF001892 [si]
  aha [si]
  hta [si]
  
  Note that searchers may use this field to limit to or exclude the unique HealthSTAR citations in PubMed.
  
  For example: hospice care AND (aha [si] OR hta [si])
  
  
• The following journal subsets are now available to search:

For example: baseball AND jsubseta

Please note that there is no field qualifier; just use the search value.

• To search for citations with abstracts in PubMed use the value hasabstract.
  
  For example: baseball AND jsubseta AND hasabstract
  
  Again, no field qualifier is needed.
  
  
• A Consumer Health link to MEDLINEplus has been added to the sidebar on the PubMed Home page.
