Aside from the actual diplomatic documents and some encyclopedia entries, there is only rather meager information available online dealing with the Paris Peace Conference and the resulting peace treaties.  There is much more material available online in scholarly databases such as Proquest or JSTOR, but access to that material is not without charge.
