The science of history attempts to narrate the past of the world, to define it through the eyes of the present and to outline the future. Placing man at its centre, it deals with all his activities, at times touching and at times trespassing the fields of other sciences. The demand for "pure history" which was formulated in the 19 th century proved to be Utopian since even the development of related sciences, like archaeology, social anthropology and later cultural studies could not manage to define it. The essence of historical perception presupposes that history draws its material from the whole of human experience and the latter's interaction with nature. History in the twentieth century, with renewed "adaptability", developed channels of constant communication with the other Humanities and borrowed methods and tools, mainly from psychology, sociology, ethnology and the economic studies. In reality, many histories were developed :  history of communications, of arts, of sexes, of explorations, financial history, history of mathematics and physics, of medicine and biology and numerous others. Every cognitive field has its history and all together constitute history. Historical information and knowledge is to some extend a case of perspective. Scientific conflicts may continue undiminished among specialists, but in reality and in the practical applications in knowledge management every interested party known where to search for each category of information. In our activities in FHW the term "historical information" is used almost as a synonym of "cultural information" and is not different from the commonly accepted term. It includes information about the perceptions, the work and the activity of people or groups with obvious and direct consequences to the structure and function of society, as well as the interaction of society with the natural world. In its wider meaning the term "historical information" deals with man’s culture as a whole and its field of interest coincides with the one of the memory institutions: museums, archives, libraries.
