The article postulates a look at the problem of literary (general) language norms, considering the evolution of the linguistic system caused by the passage of time. In the diachronic view, the linguistic system of the language has a variant nature, wherein the level of intensification of variance is dependent on the depth of systemic structures. In diachronic research, one should accept the existence of a variant level of the superficial system and to a large degree the invariant level of the deep system. This assumption allows for discussion about an immanent norm, inherent to the ethnic, national language in an organic way, precisely connected with the tendency of the language to improve itself, and also about a textual norm being the reflection of the variant level of the superficial linguistic system. In the XVI century, in the Polish language, a reconstruction of the structure of the language as the result of extralinguistic factors such as print, in effect led to an intensification of normalization, particularly in printed texts. At this time, there came into existence so-called particular norms, i.e. a catalog of normative decisions characteristic for individual publishing houses, e.g. norms unique to the Publishing Houses of Hieronim Wietor and Florian Ungler.
