The publication of the catalog of publications with dedicatory inscriptions is of great importance for the research of various aspects of the personality, biography and work of Mikhail Bakhtin. It provides new opportunities for clarifying and even revising certain facts of his biography. The authors note that despite all the efforts of Bakhtin’s studies, his biography in many respects remains a mixture of real facts and various legends, and the task of creating a complete biography of the thinker is still far from being solved. The review highly appreciates the new publication, which reveals the potential of the collection of Bakhtin’s library and especially books with dedicatory inscriptions as a source of historical and biographical information. It values any facts that can shed light on Bakhtin’s daily life, his relationship with official academia, academic and research institutions, the degree of his recognition in the academic environment, the impact of his ideas on his contemporaries and younger generations of scholars. The first book in the list of donations to Bakhtin is dated 1943, and the most recent was given to him shortly before his death on February 1, 1975. The review introduces new documents, such as the inscriptions of Nikolai Lyubimov, a translator of the novel by Francois Rabelais, and Gennady Pospelov, a theorist and historian of literature. To a great extent, the history of the inscriptions becomes the story of the reception of Bakhtin’s ideas, the attitude to his works and personality during several decades. This allows a researcher not only to clarify the specific facts of Bakhtin’s biography, but also to understand some features of various periods of his life. The catalog contains 234 inscriptions on 227 books and 5 journals, each of which is valuable for researchers. It includes the illustrations and photographs of the books and journals containing these inscriptions, which increases the value of this book. So, if needed, a reader can compare the existing inscriptions and the proposed decryption. Each of the inscriptions given in the book deserves to be studied and considered in the context of Bakhtin’s biography and works. Bakhtin’s full biography has not yet been created, and the catalog allows not only clarifying certain facts of his biography and surrounding, but also clarifying certain scenarios of Bakhtin’s relationship with formalists (Viktor Shklovsky, Lydia Ginzburg), with the scholars of the Moscow-Tartu Semiotic School (Yuri Lotman, Vyacheslav Ivanov), and with the representatives of official Soviet literary criticism (Leonid Timofeev, Alexander Revyakin). The review examines the inscriptions of Bakhtin’s colleagues and students, Bakhtin’s inner circle and their acquaintances (Ivan Kanaev, Judith Kagan, Mikhail Alpatov), and Bakhtin’s “younger circle” (Vadim Kozhinov, Sergey Bocharov, Georgy Gachev). The authors draw the reader’s attention to a remarkable detail of the digital era – the electronic version of the publication which has been available on the website of the National Library of the Republic of Mordovia named after A.S. Pushkin since 2020.
