What are Scopus secondary documents?

Secondary documents are documents that are not indexed in our database for three possible reasons:

• They are retrieved from the references or citations of the documents that are covered by Scopus.
• Scopus is unable to match documents with certainty due to incomplete or incorrect data.
• There is missing content.

To view these non-Scopus references, click ‘View secondary documents’ above your search results.

Note: You will not be able to open these documents or view the abstract.

For some secondary documents, only certain fields in the citation are available to search. This means that if you search the Abstract field, but an abstract is not available for the reference, that reference will not be included in your search results.
