Key article

A key article (or book chapter) is one that provides many references to other publications so you move towards being able to say: "I know what others have done before that informs and connects with my project." A review article or an examination of a relevant controversy can fit the bill well. It is relatively easy to find an article that matches your project and gives you entry points, but for a key article you need to find something that is much more than entry points or an affirmation of your gut feelings.
