In this paper the disciplinary context of the semiotic textological research is described and commented. The disciplines of this context belong to the following four classes: (a) the linguistic disciplines (grammar and text linguistics), and (b) the disciplines of the textological neighbour-hood (poetics, rhetorics, narrativics etc.) – on the horizontal level; (c) the disciplines of the inter-disciplinary foundation (philosophy, semiotics, theory of communication, psychology, sociology etc.), and (d) the disciplines applying textological instruments (humanities and sciences) – on the vertical level. For the adequate elaboration of the semiotic textology it is necessary to know the mutual relations existing among these four classes.
