In launching a new journal we feel the need to explain the reasons why the Centre for Studies on Federalism takes this initiative, characterised by a range of specific features. Several interesting scientific journals in English devoted to federalism are already issued all over the world. They are generally focused on one geographic area in particular, on certain levels of government or on specific academic disciplines. Therefore we believe there is room for a new interdisciplinary journal to consider federalism – federal institutional arrangements as well as potentially federalising processes - at all levels of government. The very name Perspectives on Federalism stresses that the journal will consider federalism from different disciplinary, geographic and theoretical perspectives.
