For those of you new to Human Rights or simply in need of an easy set of reference tools I would encourage you to bookmark the UN human rights homepage. It has links to the key UN human rights treaties and offices (including a link to the Office of the High Commissioner for Human Rights).
I also think you should bookmark the Human Rights Watch website. My friends at HRW have some of the very best country reports available. I will frequently link to them but you may want to add that link to your own set of bookmarks.
