Hi! -- I've just bought and installed EndNote X2 for Windows, a major upgrade from the v7 I've been using for years. I have converted my old library to the new format. In the old v7 library, I had created a custom field I called "DOI Number" into which I put the doi numbers from papers. The data did carry over into the new, converted X2 library, but it's still in the "Custom 1" field. Of course, v7 was around before doi numbers became common, so there was no built-in field for them, but X2 has its own field for that. How to I tell X2 to shift the information in the Custom 1 field to the new, built-in DOI field? I can't imagine that there isn't a way...but I can't seem to find it for some reason! Any information would be greatly appreciated! Thanks in advance for your time and help!
