Oxford Handbooks provide relevant and up-to-date overviews of the state of research in various disciplines. In their contribution to the Oxford Handbook of German Politics, Suzanne S. Schüttemeyer and Sven T. Siefken examine the German Bundestag as a "core institution" at the center of the constitutional order of the German political system.


Parliamentary Party Groups (PPGs) are the central institutional link between voters, parties, and parliaments. In its current composition, no less than 16 PPGs are present in the Croatian Parliament (Sabor), a peak value in European comparison. The trend towards fractionalization in Sabor has steadily increased in recent years. The article explores the causes, compares „PPG Thresholds“ internationally and outlines reform options.

The digitalization of human life has impacted many aspects of politics in the last two decades. Intra-party decision-making is one of them. However, not much is known about how intra-party selectorates evaluate the digitalization of a crucial decision-making process. Claire Bloquet, Isabelle Borucki and Benjamin Höhne ask whether party members who participate in candidate selection support online consultations - or not.

Benjamin Höhne writes about the fundamental processes of candidate selection in Germany, the role of the parties and future challenges in his contribution to the edited volume by Thibault Muzergues and Dan Scadutoder. The publication of the International Republican Institute (IRI) brings together ten case studies on the selection of parliamentary candidates. The volume is freely available on the IRI site.
