The U.S. Copyright Office offers a searchable list of federal copyright infringement cases. The list can be narowed by jurisdiction and/or category (some categories to consider include internet/digitization, music, and computer program). Each listing provides the full case name, year, and outcome which links to a brief explanation of the major issues involved in the case.
The New York Times (accessed via ProQuest) is considered a paper of record, especially in copyright cases. Use selected keywords to help to find articles connected to your case. Citations are included! Username and password available here.
Consult Wikipedia for an entry on your case. Note, this is not your article. Use Citation Chaining, the process of consulting the sources cited to find articles that have been connected to the discussion of your topic.
Upgrade your Google search by using the News Tab, filtering by date (under Tools at the top right of the search screen) to find the most recent articles connected to your case.
Purdue's OWL - Electronic Resources provides both a model for the key parts that a citation should include and sample citations to help your work.
Articles retrieved from a database like ProQuest should be cited using the MLA 9 (title case) citation provided by the database. Articles found online can be cited with the help of the MyBib extension OR by following the sample citations provided by OWL. (It is often easier to cite an online source independently. Really. I promise. Give it a try!)
If you chose to use MyBib use the MyBib extension in the Chrome browser.
