IMF,NBER and World Bank recognition of references

Dear Endnote,

I have noticed that Endnote recognises automatically, when importing pdfs, the associated references if these come from journals but it doesn’t do the same for papers that come from the IMF, World Bank or the BIS. The reference fields for the latter have to be manually included.  is my observation correct and is there a way to correct this?

many thanks

Konstantin
