The object of the study is library printed publications as a component of the national scientific and cultural heritage. The subject of the study is technological methods of converting printed publications in the system of preserving library funds. The purpose of the study is to trace the changes that have historically occurred in the technology of converting library printed publications, to determine the prospects for reformatting paper documents. Relevance of the study. The topic of the study is actualized by the full-scale russian invasion of Ukraine (2022), during which, in particular, centers of national science and culture are being purposefully destroyed. A number of domestic libraries are being destroyed and damaged. In view of this, the policy of reformatting library printed publications is one of the tools for implementing the strategy of preserving the national documentary heritage and protecting it, primarily, from the consequences of military actions. The relevance of the study is also due to the requirements of modern users to obtain convenient access to various copies of printed documents from the library fund. Methodological basis of the study: analysis, synthesis, historical, terminological, comparative, generalizing approaches. Scientific novelty. Expansion of professional ideas regarding technologies for making copies of printed documents, determination of the spectrum of possibilities for their use in the library and information service system; outlining directions for further conversion of library printed publications in the system for preserving library funds. Conclusions. The presence of various copies of printed documents and their involvement in everyday library and information service determines the optimization of scientific, educational, production, cultural, educational and other social processes and is an important factor in innovative national development. Prospects for further research. In the future plans, it is planned to more widely explore the information and search capabilities of digitizing printed documents and determine the ways of a further national strategy for preserving library funds.
