Where can I find the text of League of Nations resolutions?
Since the League of Nations disbanded over 60 years ago, it is not easy to find resolutions that it passed. Some are available through the United Nations, which was created after World War II to replace the League. Others are available in digitized form in from various libraries.
The best resource of which I am aware for League of Nations documents is this link from the Bodleian Library at the University of Oxford. It has a number of useful links that can be of help to you in finding documents produced by the League of Nations.
