Order, as a philosophical category, comes from the Greek philosophy and is one of the principles of information organization. The nature of order as well as of its origin and its presence within the classification systems of Information Science is analyzed. We conclude that this order is introduced by librarians without, however, subjective or relativistic consequences. The constructed "documentary cosmos" has objective ontological basis from the "informational being" of the subject; thus, it has regularities and characteristics that can be objectively studied.
