How does EBSCO prevent duplicate results from appearing in the search results list?

Multiple instances of the same record are removed or "de-duped," and the one with the highest relevance ranking score is displayed.

Duplicates are removed by comparing the following citation metadata:

 

  • Title
  • Author
  • Date published
  • ISSN or Journal name or ISBN

Catalog records are never considered for de-duplication; catalogs can have multiple copies of the same item. (EDS only)
