The system of linguistic support (LS) of the automated library-information system (ALIS) of a scientific subject library is considered on the example of the Central Scientific Agricultural Library (CSAL). The following elements of LS are considered: linguistic tools, tools of formation and support of information retrieval languages (IRLs), methods of IRL indexing, regulatory documents. Their role in the LS system and the effective functioning of the ALIS is determined. The efficiency of ALIS depends on the choice of LS. IRLs are the main element of LS, since they form and structure information arrays, turning them from a siloed, formless pile of information into a systematized logical system. The main objective of the IRLs is to present information in a contracted form and ensure its search afterwards. To meet the diverse needs of library users, there should be several IRLs, because there is no ideal single IRL that simultaneously performs all the functions of linguistic tools and provides all the information tasks solved by ALIS, for example, the processes of database preparation; preparation of information publications; distribution of information flows between users. The structure of the linguistic tools of the CSAL’s ALIS includes several IRLs: language of bibliographic description, the Industry-Specific Classification Index (Rubricator) for Agriculture and Food, Universal Decimal Classification (UDC), the Information Retrieval Thesaurus on Agriculture and Food, language of keywords. Their functions in the CSAL’s ALIS are considered. The listed IRLs, except for UDC, are search linguistic tools in the OPAC-Global ALIS. It is concluded that most promising is the use of IRLs specially designed for an automated system such as the Industry-Specific Rubricator and Thesaurus.

The article examines the activities of the Library of the Academy of Sciences of the BSSR in 1943–1950. On the basis of archival sources, data on the damage caused to the library by the Nazi invaders was analyzed. During the years 1943–1945, the main focus was on restoring library collections. Data on assistance in the restoration of collections by libraries, educational and scientific institutions of Moscow and other cities of the USSR are summarized. The second half of 1945 and the beginning of 1946 were marked by the search and return of books from library collections taken by Nazi invaders to Germany. Despite significant difficulties due to lack of financial resources, premises and personnel, the library collections were gradually growing. The total book collection of the Library of the Academy of Sciences of the BSSR in 1948 exceeded the pre-war level. The move of the library in 1945 to the temporary building of the Academy of Sciences on Moskovskaya Street caused a radical change in the work of the library and made it possible to move from the formation of a book collection to its use and service to readers. In January 1948, thanks to the relocation of the library to the restored building of the Academy of Sciences, the conditions for reader services were significantly improved. The increase in the number of readers, library visits and document circulation depended not only on the quality of the library collections, but also to a large extent on the library premises. Throughout the recovery period, the library experienced a huge need for additional premises, special equipment and staff expansion.
