Paper focuses on the role of translation in building and widening of sociological horizon. It points out the significance of quantity, quality, up-to-dateness, availability, and indispensability of translations. It also analyses functions of didactic texts' (textbooks and readers) translations defining, together with academic publications, the borders of sociological mainstream canons. The paper shows how translations have broadened sociological mainstream by gender perspective, and mentions crucial translations from this field. The analysis includes examples of texts not present in the canon - still not translated into Polish or translated too late, and those translated early enough to enter the canon.
