The knowledge management uses a set of methods, techniques and tools to systematize and share knowledge and to make the environment propitious for generation, appropriation and use of knowledge. Conceptual maps are one of the knowledge management tools. These maps show what knowledge the organization has, who create it, in what way it is created and how this knowledge can be used by the organization. Thus, this research tried to understand knowledge importance at organizations environment and also the use of conceptual maps at this environment. After, it will be created a conceptual map to visualize the organizational knowledge in the Information Science Department at Sao Paulo State University, Brazil. The concepts to build the map will be extracted from the department teachers using the Delphi Method.
