St. Petersburg : Profession, 2023. 334 p. (The textbook for the bachelor’s degree course).The textbook continues the tradition of “Professija” Publishing House of publishing practical guides, reference and educational literature in bibliography. All the publications are in great demand, both among practitioners, the faculty and students. For example, the “The Bibliographer's Handbook” has gone through four editions. The textbook by I. G. Morgenstern for many years has been the main source of knowledge for the students in the context of the “General Bibliography Science” course. The peer-reviewed textbook by O.P. Korshunov, N.K. Lelikova and T.F. Likhovid is published in its second edition. The authors of the textbook present the material based on the system-activity, documentary, information and communication concept of the general theory of bibliography origins as introduced by O.P. Korshunov. The textbook consists of three sections: “Fundamentals of the theory of bibliographic information”, “Bibliographic activity – the central category of the theory of bibliography”, “Bibliography science – the science of bibliography”. The lists of recommended reading are provided at the end of each section. A Dictionary of Basic Terms is a valuable addition to the main text. The textbook material is significantly amended, as many new standards on bibliography were introduced and changes were made to the terminology, with the factual material updated.
