In 1863 he defended his thesis for a master's degree in Russian literature "On the Epics of the Vladimir Cycle", in which he proposed a historical point of view on the origin of epics: he indicated, in particular, that the epics of the Vladimirov cycle are a reflection of the Kiev specific period. After the defense, he did not last long in the Ministry of Finance and in 1864 he moved to the Central Statistical Committee and until 1882 took an active part in its work, as well as in international statistical congresses. Since 1868 – professor at the Saint PetersburgArchaeological Institute. In 1882 he was appointed assistant director of the Imperial Public Library.

He began his literary activity as a student; posted a long series of historical and literary articles and reviews in "Domestic Notes", "Dawn", "Russian Herald", "Ancient and New Russia", "Russian Antiquity", "Russian Archive", "Journal of the Ministry of Public Education", "Historical Bulletin", "Russian Philological Bulletin" and others. The most important of them are devoted to Simeon Polotsky, Lomonosov, Vasily Maykov, Sumarokov, Krylov, the history of Russian journalism, the ancient Russian story, the history of Russian superstitions and are collected under the title "Essays from the History of Russian Literature of the 17th and 18th Centuries".

In 1891, he edited and characterized the collection of critical experiences of his brother Valerian. In his master's thesis, Maikov showed significant scientific independence. In an era of almost undivided domination of the mythological explanation of folk poetry, he put forward a historical point of view on the origin of Russian epics, with which scholars of this dark issue are still reckoned with. In his opinion, the Russian epic is a true echo of Russian historical life, and, in particular, the epics of the Vladimirov cycle, the Kiev specific period. Many heroes of epics – Dobrynya, Alyosha Popovich, Sadko, Ilya Muromets – the author, comparing the annals, considers them to be truly existing; in household details, he indicates traces of the actual historical life of 10th–13th centuries. Epics arose, in his opinion, among the squads. He died on April 20, 1900. He was buried in Saint Petersburg at the Novodevichy Cemetery.
