This thematic issue introduces the multifaceted nature of contemporary public policy-its multi-level, multi-actor and multiissue features-using the case of higher education policies from around the world. To do so, this introduction first describes how higher education as a policy sector should be garnering far more attention from scholars interested in political, economic and social transformation. A framework for identifying and accounting for how the 'multi-s' characteristics configure and re-configure public policy is then introduced. Next, this thematic issue's contributions are summarized with highlights of how they bring to life the different 'multi-s' features. This introduction concludes with a discussion of what the proposed framework of the 'multi-s' offers to studies of higher education policy coordination. In so doing, the objectives of this thematic issue are to highlight what the case of higher education policy coordination offers to studies of public policy and to initiate a dialogue between all social scientists and practitioners interested in the increased complexity of governing, producing and using knowledge today. This thematic issue of Policy and Society focuses on the increased multifaceted characteristic of contemporary public policy (Peters, 2015). Using the case of higher education policies from around the world, we highlight the multi-level, multi-actor and multi-issue-'multi-s'nature of public policy in areas of growing international and political attention. The global shift towards knowledge-based economies and societies has placed 'knowledge' at the core of contemporary public policy and policy-making. The governance of knowledge, however, is not a neatly contained policy coordination exercise: it requires collaboration across multiple policy sectors that may have previously experienced very little or less interaction. A non-exhaustive list of relevant policy areas includes higher education, research, trade, foreign policy, development and home affairs (migration). Higher education policy coordination is thus permeated with respective sectoral concerns, with discussions taking place across distinct policy arenas, sometimes in silo, both inside and
