Periodicals Archive Online
ProQuest's Periodicals Archive Online has some rich metadata for journal articles that would be a valuable addition to the PCI.
Dahl, R.A. 1957, "The Concept of Power", Behavioral science, vol. 2, no. 3, pp. 201
There is no metadata present in the PCI but Proquest have full details (Proquest document ID - 1301269515) and would enhance our use of this resource if it existed in Primo.
