The International Relations and Security Network (ISN) is an open access information service established in 1994 as an online project of the Center for Security Studies at the Swiss Federal Institute of Technology.
The mission of the ISN is to "promote greater knowledge sharing, learning and collaboration" and they work with "the world’s leading think tanks, universities, research institutes, NGOs and international organizations ... to offer our users a broad selection of views and opinions on the major issues of our day."
There is a wealth of free information in the ISN Digital Library including research reports, working papers, and other publications with some access to selected primary resources and a useful annotated list of links to blogs, podcasts and other web resources. The materials are organized by subject (for example 'human rights' and 'law') and by geographical region (including a handful of documents dealing with Canada) and includes an advanced search option.
