The May 2016 release brought an interesting functionality to the Primo Central Index (PCI): The new "Citation Trail" capability enables PCI users to discover relevant materials by providing cited and citing publications for selected article records.
At this time the only data source for the citation trail feature is CrossRef, thus the number of citing articles will be below the "Cited by" counts in other sources like Scopus and Web of Science.
