Zotero not recognizing DOI
I've been trying to add a few articles via DOI, and I seem to have particular trouble with TESOL Quarterly. This article, for example (http://onlinelibrary.wiley.com/doi/10.1002/j.1545-7249.2008.tb00207.x/abstract). Adding the DOI to the magic wand in Zotero returns no results. Fortunately, I have the PDF, so I can drag that in and retrieve metadata, but why would Zotero not recognize the DOI?
