The Cycle of Social Sciences and Humanities in Library and Bibliographical Classification

In the middle of the 20th century in our country the national Library and Bibliographic Classification (LBC) tables for universal and specialized scientific libraries were published for the purpose of organizing book collections, catalogues, card catalogues, bibliographic descriptions in indexes. During its existence, a system of scientific and specialized versions of classification tables for libraries of different types, depending on the acquisition of their collections, has been created. At present the LBC exists in three main variants: full, medium and abridged schedules, which differ in the degree of detail and depth of disclosure of content, but are consistent with each other in structure and indexing. They also preserve the principle grouping and sequence of sciences in the main series: first comes the natural sciences cycle, then the applied and technical sciences, and finally the social and humanities cycle. Classification as a form of knowledge organisation has the task of revealing the content of printed works in the most complete way. The cognitive nature of library classification is connected with the development of science and changes in its various fields, with the change of scientific paradigms, the formation of new research directions, approaches and methods, with interpretations of modern phenomena. The arrangement of knowledge about the surrounding world is based on the provisions, rules, principles and methodological foundations laid in the classification as tools of cognition. The article analyses the socio-humanities complex in the LBC Middle tables, taking into account the changes in the sciences for a comprehensive disclosure of the content of the works of print.
