The WW1 Document Archive is a portal created at the Brigham Young University for the history of the First World War with special attention to documents. This portal has the form of a wiki. In particular documents pertaining to diplomacy, such as conventions, treaties and official papers, can be found here easily. The portal has a biographical dictionary and a section with links to digitized books. Very useful is the section on digitized diaries and personal reminescences. The section on medical history, The Medical Front, is interesting, too. The portal brings also a very detailed web directory. The portal is connected with EuroDocs: Online Sources for European History.
