In 1902 Znanie started publishing the "Complete Bunin" series; five volumes appeared by the year 1909. Three books, "Poems (1903)", "Poems (1903–1906)" and "Poems of 1907" (the latter published by Znanie in 1908), formed the basis of a special (non-numbered) volume of the "Complete" series which in 1910 was published in Saint Petersburg as "Volume VI. Poems and Stories (1907–1909)" by the Obschestvennaya Polza (Public Benefit) publishing house. Bunin's works featured regularly in Znanie's literary compilations; beginning with Book I, where "Black Earth" appeared along with several poems, all in all he contributed to 16 books of the series.
