Did you know? Searching by DOI

If someone has a DOI, and no other information about an article, how do you search for that article?
You can go here, to The DOI System:
http://www.doi.org/
Scroll down the page, and look for the section: Resolve a DOI name
Copy and paste (or type) your DOI into the search field, and click the submit button.
Presto! The article's information is displayed. Now you can search by journal title, article title, author, or whatever you like.
