My old version of EndNote used to include a feature which is no longer there. You used to be able to manually insert the Reference Type as Report, which was a bit generic but suited the different types reports I use. Now I am using Endnote X8 this feature seems to be missing when I manually add a reference. I don’t know how else to cite reports from the Intergovermental Panel for Climate Change because it is not a webpage nor is it a working paper.
Thanks!
