Empirical research is generally published in scholarly, peer-reviewed journals.
The MJC Library subscribes to several databases providing access to peer-reviewed journals. Not only do these databases provide access to this type of material, but they allow you to limit your searches to retrieve only peer-reviewed content.
A DOI can be used to cite and link to electronic articles. A DOI is guaranteed never to change, so you can use it as a permanent link to any electronic article.

You can Google a DOI to find an article, although you may still have to sift through search results. To go straight to the source, you can also use a DOI resolver like the one linked to above from the International DOI Foundation.
