A knowledge map presents the dimensions of a knowledge area and probes its logical and, at times, conflicting aspects and delineates how they are all intertwined. It gives a comprehensive conceptual map of existing knowledge with links to online resources.

Besides being comprehensive, a knowledge map is also eclectic, reflecting different strains of direct and tangential thought on a particular knowledge area.

Knowledge maps are extremely useful because they not only lay down an empirical and conceptual way to knowledge, but they also lead you to different avenues of discovery through serendipity.
