Abstract: The subject of this research is the establishment of substrate-attributive model of the information substrate of information culture. The object is the information culture as a sociocultural phenomenon. The work substantiates the idea that information culture has an information substrate, represented in three elements: civil, social, and anthropological; information, sociality, values, norms, traditions, subjectivity, objectivity, and virtuality are considered its attributes; the generic diversity  of information culture determines its modes. This work is continuation of research of the phenomenon of information culture in the articles of the scientific journals "Philosophical Thought" and "Conflict Studies" of the Nota Bene publisher. The scientific novelty lies in the fact that the author substantiated the necessity and possibility for establishing a substrate-attributive model of the nature of information culture, which allows defining its basic structural elements, properties, specificity, as well as reveals the factors and mechanisms of origination and development of such sociocultural phenomenon. The conducted research will be valuable in further examination of the impact of information culture upon the transformation of generic qualities of a person: consciousness, activity, communication, and language in the conditions of evolvement of the information society.
