In this article, we introduce a unique data set containing all written communication published by the German Bundestag between 1949 and 2017. Increasing numbers of scholars make use of protocols of parliamentary speeches, parliamentary questions or the texts of legislative drafts in various fields of comparative politics including representation, responsiveness, professionalization and political careers or parliamentary agenda studies. Since preparing parliamentary documents is rather resource intensive, these studies remain limited to single points in time, types of documents and/or policy areas. The long time horizon and various types of documents covered by our new comprehensive data set will enable scholars interested in parliaments, parties and representatives to answer various innovative research questions related to legislative studies.
