In his 1995 monograph, Apresyan suggests that it would be extremely interesting to investigate the means of expressing the definiteness/indefiniteness opposition in languages that do not have articles. In this paper, I will attempt to find possible correlations between the organization of discourse and the positions in which the (in)definite nominals may appear within a sentence of Russian. I will examine the information structure of Russian sentences and, based on the previous analyses, provide a new account of their organization with respect to information packaging. I will then look at various nominal elements contained in certain parts of a sentence and arrive at a system describing the distribution of NPs in Russian with respect to the information structure. The ultimate goal of this paper is to establish and motivate a system of correlations between various types of NPs and functions of information structure. This goal will be achieved by determining which characteristic of a NP may serve as a criterion allowing to provide a one-to-one mapping
