EndNote X4’s PDF import feature could be very useful.
However, citations downloaded from PubMed have significant advantages such as consistency of style, inclusion of an abstract, keywords, etc.
Can anyone think of a way to merge citations (not libraries) so that references downloaded from PubMed and those automatically generated by EndNote could be fused together? Even a manual means of pairing citations to merge would be very useful.
I no longer have X3 installed, but if I remember correctly, X3 and previous versions that supported PDF file attachments allowed the PDF files to be dragged and dropped between citations in EndNote. X4 does not allow PDF file attachments to be dragged and dropped (anymore).
Without either of the above features, I do not think that the new PDF import facilities of EndNote X4 unfold their full potential.
