It is taken for granted that criminology deals with a broad spectrum of knowledge about delinquency, crime, and criminal justice. Although, specifically in Germany, closely connected to the penal law it is based on several sciences such as psychology, psychiatry, sociology, political sciences and others. As a result of empirical research, criminology can contribute to problem solving / decision making in politics, criminal justice, police and social services as well.

Obviously, it is necessary for all sciences to prepare knowledge and information dissemination with the assistance of databases. Documentation of criminological literature and providing for a database as well, has played a pivotal role since the founding of the KrimZ (1986).
