Cause
EBSCOhost has been putting the full author name in the aulast parameter, like so:
![aulast.PNG](https://knowledge.exlibrisgroup.com/@api/deki/files/68383/aulast.PNG?revision=1)
Parsers and linkers expect only the last name in the aulast parameter or a full author name in the au parameter, so outbound linking fails. When manually corrected to contain only the author's last name in the aulast parameter, the article links successfully.
