I expect Endnote to be much smarter in locating reference updates. If I can find refernces manually, than Endnote should be able to do so automatically. Minimally, Endonote should be able to find the complete reference when I provide a title, first author’s last name and publication year.
I can nearly always locate references by conducting a Google search on the title which will lead to a doi. Providing the doi to Endnote then retrieves the correct reference. Perhaps this can be scripted in Endnote.
Alternatively, Endnote could just index all dois with bibliographic information and eliminate all the complexity of searching databases entirely. I hate that online searches in Endnote rarely return anything useful. Computing power and storage is cheep enough these days to make such an index feasable.
