Primo Central Index (PCI) is a centralized Primo index that encompasses hundreds of millions of records of global or regional significance that are harvested from primary and secondary publishers and aggregators. The number of records is constantly growing as additional data sources are added.
The records include a mix of scholarly material – primarily articles and e-books – but also conference proceedings, newspaper articles, and more. In addition to citation metadata, many records include abstracts and some also include full text. The full text in PCI is indexed and used for discovery, not for delivery.
PCI is maintained by Ex Libris and offered as a service to all Primo customers as a search scope and to MetaLib customers as a resource.
