Introduction to sources for International Law

The Hartley Library holds a range of materials to support the study of international law.  If you are looking for a particular publication, first check Library Search, which provides access to the library catalogue.

Printed law reports are shelved at Law Reports: International.  Books on International Law are shelved at JX 2000 onwards, whilst those on Comparative Law are shelved at KX.  Most books on the law of Human Rights are at JX 4001.  Periodicals, including those for Human Rights are at per K.

The print collections are complemented by our various online sources.  In particular, Westlaw, Lexis Library and HeinOnline offer an abundance of relevant primary and secondary legal materials.   Some of our e-book packages are worth exploring for texts on international law, especially ebrary and the Intersentia Human Rights Collection.

There are also extensive free web sites, especially for primary sources including  treaties and case law.
