We live in a world of science. Yet this is impossible without a legally guaranteed freedom to practise it. Findings with regard to the elements of such freedom can be deduced from an analysis of international and domestic provisions and principles. There are a plethora of international institutions, legal rules and global norms for the purpose of the international governance of science. The institutions and rules are to be interpreted in light of this freedom to guarantee the continuous existence of the knowledge-based society by means of a global administrative law of science. These aspects were analysed in a research project funded by the German Research Foundation. The book's purpose is to present the jurisprudential results. In addition, empirical results are collected in a freely available database. This study is composed of 5 parts: The Concept of Science; Global Administrative Law; Constitutional Basis - The Freedom of Science; Institutional Design; and, Governance Mechanisms.
