MEDLINE^® Reloaded on Dialog

MEDLINE (Files 155/154) is reloaded every year to include the U.S. National Library of Medicine (NLM) revisions to the Medical Subject Headings (MeSH®) and to introduce new MeSH terms previously not used in MEDLINE. Citations going back to the earliest records for 1966 are updated wherever necessary with the new MeSH headings. The following features were implemented in this year's reload on Dialog.

New Enhancements

Added are the following new fields, searchable and displayable in all formats:

• Main Citation Owner (OA=) identifies the organization responsible for the citation.
  
  
• Other Citation Owner (OB=) identifies organizations other than NLM that have contributed to the citation.
  
  
• Abstract Source (OC=) identifies the organization that contributed the abstract of the citation.
  
  
• Mission Name (MI=) identifies the space flight mission (e.g. STS-70, APOLLO-SOYUZ PROJECT, etc.) included in the NASA/Spaceline records that are now available in MEDLINE.
  
  
• Record Identifier (RI=) is an 8-digit ID number for non-NLM records, such as records from NASA/Spaceline.
  
  
• Date of Electronic Publication (EP) is displayable only.

The new list of Record types (RT=) includes: In Process, Completed, Out of Scope. "Out of Scope" record type has been added to this field to identify those in-process records that do not meet NLM requirements and thus never become completed.

Further information on the changes for 2002 is available in the April issue of Chronolog (see MEDLINE® Changes for 2002).
