To assess the socio-cultural, scientific and pedagogical novelty and significance of the annual reports of the international forum “Crimea”, read by Ya. L. Shraiberg in 2001–2021, the key words are used – the neologisms “bibliometamorphosis” and “Bibliologos”. Metamorphoses (transformations, transformations) embody the universal variability of the world, and at the same time its stability, since the transforming object does not disappear without a trace, but is transformed into a related entity. Therefore, a book or a library in today's changing world should remain a book and a library, despite external modernization, digitalization and globalization. Bibliometamorphic institutions are religion, ideology, science, art, education, which perform social information and communication functions through book communication (written texts). The bibliologos (literally, “book mind”) performs in a civilized society the function of a productive force that ensures the creation, preservation, and use of the bibliosphere. The bookish mind is realized in two ways: first, the animate Bibliologos in the form of social groups of subjects of the bibliosphere; secondly, the materialized Bibliologos in the form of scientific, educational, normative and administrative texts of intellectuals-scribes devoted to the bookish mind and culture. The animate Bibliologos is the collective mind of library, bibliographic and book professionals (practitioners, scientists, educators), government and commercial figures, bibliophiles, printing engineers, readers' asset directly involved in the production, transformation, preservation and distribution of written and printed works. The technical, political, humanistic metamorphoses of the Logos of modern Russia are considered in detail. The key role of libraries in the socio-cultural metamorphoses of the post-industrial society is shown. The article concludes with a call for continued regular review of library and information science and practice.
