– Combine & Use Manifesto Data with other Datasets ("A Database of Political Parties Worldwide") links datasets on political parties and provides an online encyclopedia about parties and their history as recorded in social science datasets. The Manifesto Project's party codes are a core component of this project. Thus Party Facts currently provides links of manifesto parties to more than 60 other datasets (such as ParlGov, CHES, CLEA, ESS, ParlSpeech, Wikipedia).
