The book of Doctor of Philology N.L. Leiderman is devoted to the study of a new creative method (postrealism), which crystallized in Russian literature during the twentieth century. The book consists of 2 parts. The first part is a theoretical essay. Here we consider the genesis of the new method, its structure, the process of maturation on its basis of a whole literary direction with its own currents. The second part presents analyzes of the works of Mandelstam, Akhmatova, Pasternak and other authors, which are based on the aesthetic principles of postrealism.
