This tutorial is about interpreting journal article citations in print and online indexes. Most indexes have their own citation styles and it is impossible to illustrate them all. The purpose of every citation style is to concisely identify a published work for use in bibliographies. For illustration purposes this tutorial uses its own citation format. The concepts embodied can then be generalized to other citation styles. The screen resolution needs to be set to a minimum of 1024 x 768 or higher for the tutorial to work. The tutorial also needs as much screen space as possible. In particular, there should be no frames or menus to the left or right of the browser window.
