I've been browsing through a lot of scientific papers lately, and was struck by just how bad Nature's doi resolving sometime is. Try this for example: http://dx.doi.org/10.1038/nature04268
You get to a page with the article title, the authors, and the reference. But no sign of a link to the abstract, the HTML article, or the pdf article!?
I've also found a discussion on various pdf/paper archiving services. I'd like something that integrates well with EndNote, any ideas?
