The article provides a critical analysis of two literary-biographical works of a famous lawyer, poet and novelist, literary critic of the 19th and early 20th centuries. Serhii Arkadiyovych Andreevsky, with the aim of evaluating these works as sources from the history of the Luhansk region. A set of methodical remarks regarding the assessment of the accuracy and reliability of information contained in literary and biographical works and the results of its verification by other documents has been formulated. The childhood age of the author's observations, the lack of diary notes, and a significant chronological gap between the events and the writing of the memoirs were named among the factors that affected the degree of authenticity of the historical facts. The autobiography «The Book of Death» and the poetic poem «Tomorrow Days» reflect the childhood of Serhii Andreevskii, which dates back to the 40s and 50s of the 19th century, and which he spent in the villages surrounding Luhansk – Vesela Gora, Oleksandrivka and Raivka. The question of the genealogy of several noble families of the Slavyanoserbsk District of the Ekaterinoslav Province is analyzed, as well as their land holdings, everyday life, customs and lifestyle of local landowners, significant events in their lives, descriptions of their estates, etc. Interesting, albeit limited, facts about the life of the local Ukrainian peasantry, description of the villages of that time, nature and landscapes of the Ukrainian steppe and Siversky Donets were also extracted from the sources. The obtained and critically evaluated information is very important, partly unique, since the period of the second quarter of the 19th century is extremely poorly provided with documents for researching the history of the mentioned villages of the Luhansk region.
