* Getting pdf files from a DOI
-The idea here is simple. When you visit http://dx.doi.org/doi, you get redirected to the journal site. Once you have the url for the article, you can usually compute the url to the pdf, or find it in the page. Then you simply download it.

-There are some subtleties in doing this that are described here. To get the redirect, we have to use url-retrieve, and a callback function. The callback does not return anything, so we communicate through global variables. url-retrieve is asynchronous, so we have to make sure to wait for it to finish.

We can use that data to construct a bibtex entry. We do that by defining a template, and filling it in. I wrote this template expansion code which makes it easy to substitute values like %{} in emacs lisp.

+
+
+1. go to article in WOS: http://ws.isiknowledge.com/cps/openurl/service?url_ver=Z39.88-2004&rft_id=info:doi/10.1021/jp047349j
