Most scholars view the chronicles as historical sources as well as works of art.
Vasily Klyuchevsky used them as a historical source along with the
lives of the saints.
Early period Study of the history of Old Russian chronicles was begun by
Vasily Tatishchev and
Mikhail Shcherbatov, whose work impacted the emergence of
source criticism as a science. Using Tatishchev and Stroev's method, Mikhail Pogodin discovered how the chronicles were constructed. Mikhail Sukhomlinov's 1856
On the Ancient Russian Chronicle as a Literary Monument attempted to establish the literary sources of the initial chronicle. Bestuzhev-Ryumin's 1868
On the Composition of Russian Chronicles Until the End of the 14th Century deconstructed chronicle text into annual records and legends. A new stage in the study of Russian chronicles was begun by
Alexey Shakhmatov (1864-1920). His comparative textual method compared lists and analyzed text. Shakhmatov sought to learn about the circumstances of the creation of each chronicle through chronology, printing and language errors, and
dialectic.
Modern period Starting with Shakhmatov, the main analysis of the text of the chronicles recognizes the comparison of two or more chronicles throughout their length, and not fragmentary observations. The method of Shakhmatov was developed by Mikhail Priselkov, who placed more emphasis on the historical aspect ("History of Russian Chronicles of the XI—XV centuries", 1940). Shakhmatov's genealogy was developed and revised by his followers, among whom the greatest contribution to the study of Russian chronicles was made by Nikolai Lavrov, Arseny Nasonov, Lev Cherepnin,
Dmitry Likhachev, Sergey Bakhrushin, Alexander Andreev,
Mikhail Tikhomirov, Nikolai Nikolsky, Vasily Istrin, etc. Shakhmatov's methodology formed the basis of modern
textology. The study of letopis texts has become widespread in modern Russia and other countries. Among the researchers of the second half of the XX century, the greatest contribution to the study of old Russian letopises was made by
I. A. Tikhomirov,
D. S. Likhachev, Ya. S. Lurie, V. I. Koretsky, V. I. Buganov, etc. The study and publication of the Belarusian-Lithuanian letopises were carried out by scientists from
Poland (I. Danilovich, S. Smolka, A. Prohaska, S. Ptashitsky, Ya. Yakubovsky, E. Okhmansky),
Russia (
I. A. Tikhomirov,
A. A. Shakhmatov, M. D. Priselkov, V. T. Pashuto, B. N. Florya),
Ukraine (M. S. Grushevsky, F. Sushitsky),
Belarus (V. A. Chemeritsky, N. N. Ulashchik),
Lithuania (M. Yuchas, R. Yasas).{{Cite book|language=|author=Polenov S. V. |title=The letopises of the Belarusian-Lithuanian / of Polenov S. V. // Las Tunas == List of chronicles ==
