Decisions of international courts and arbitrators, as well as judgements of national courts, are fundamental elements of modern public international law. The International Law Reports is the only publication in the world wholly devoted to the regular and systematic reporting in English of such decisions. It is an absolutely essential work of reference. The series, established 60 years ago (originally under the title of Annual Digest and Reports of Public International Law Cases), covers the years from 1919. Four volumes a year, each of some 700 pages, are envisaged. The cases are drawn from every relevant jurisdiction - international and national. The series is, therefore, the most convenient source of case law material in the field. The volumes are prepared by an experienced team under the auspices of the Research Centre for International Law in the University of Cambridge. All decisions in foreign languages are translated into English. By reason of its standing and scope of coverage, the series is widely and regularly cited in judgements of international and national tribunals, as well as in the literature of the subject. There is no question here of choosing between this series and some other. There is no other publication that even remotely provides a comparable coverage of case law in this field. The series is a must for every library that needs to provide even minimal international law coverage. It is also the most economical and efficient way of accessing the whole range of international case law material.
