Non-MeSH Indexed Citations

• Some of the citations received electronically from publishers may never become MEDLINE citations.
• These records are not assigned MeSH terms because they do not go through the indexing process.
• These records may have either the status tag [PubMed] or [PubMed - as supplied by publisher] and remain in PubMed even though they are not MEDLINE citations.
• There are three sources of these types of records:

1. Out-of-scope Articles from selectively indexed MEDLINE journals

• This may occur when a particular article in a
  selectively indexed journal is out-of-scope for MEDLINE (such as a geology article in a general scientific journal like Science or Nature).
• These citations have been reviewed for accurate bibliographic data.
• The status tag [PubMed] appears on these citations.
  

2. Articles from issues of journals published prior to selection for MEDLINE indexing

• These earlier citations will not be indexed with MeSH headings.
• Prior to late 2003:
  • the citations were not reviewed for accurate bibliographic data
  • the status tag of [PubMed - as supplied by publisher] appears
• Beginning in late 2003:
  • the citations have been reviewed for accurate bibliographic data
  • the status tag of [PubMed] appears
    
    

  Example: NLM began indexing the journal Molecular Diagnosis, with v. 4, no. 1, 1999. However, the publisher electronically supplied NLM with citations from earlier volumes. The citations from back volumes were entered into PubMed but will not be indexed with MeSH.
  
  Note: Indexing information for a particular journal can be found in the “Indexed In” field in the NLM Catalog. Use PubMed’s Journals Database to link to this information.
