CrossRef is the official DOI® link registration agency for scholarly and professional publications. DOIs, or Digital Object Identifiers, are a way of linking permanently to articles online – CrossRef has a short Flash animation explaining them here, or for more information visit www.doi.org.
Also useful on the CrossRef site is the Simple Text Query, which allows you to enter a bibliographic reference and then gives you the DOI associated with that article. If you do not have a complete reference, you can try the other tools on the free DOI lookup page.

Thanks for mentioning CrossRef. More details about how DOIs can help researchers are availalbe here: http://www.crossref.org/05researchers/index.html.
For scholars who blog, we also have a plugin available to make it easy to cite scholarly papers using the DOI:http://www.crossref.org/01company/pr/press021208.htm.
As you mentioned, the beauty of using DOIs is that they permanently link to the authoritative version of a journal article, book, proceedings paper, or other content type.
