    abstract = {This article summarizes the Correlates of War
      Intergovernmental Organizations (IGO) Version 3.0 datasets. The
      new datasets include information about the population of IGOs in
      the international system and state participation in those formal
      international institutions from 1816 to 2014. Consistent with
      Versions 2.0 and 2.3, Version 3.0 of the IGO data comes in three
      forms: country-year, IGO-year, and joint dyadic membership.},
