This thesis presents and analyzes the implemented projects of digitization of library materials in museum libraries. The first part will be dedicated to the description of the digitalization process and a brief overview of its development, application and significance today. Professional literature will further define the basic terms of museum library and museum publishing in order to explain the specificity of museum publications that museums write, publish and store. The scope and type of digitized library material will be presented in the practical continuation of the thesis, which will study and compare finished projects. By creating a representative sample based on the selection of several museum libraries and UDK analysis of the affiliation of their disciplines, a survey with chief librarians will be conducted as a research method that will present the completed projects. By asking chief librarians of different museum libraries the same, pre-determined questions, different needs of individual museum libraries in terms of library material digitization will be illustrated. A short research will present a hypothesis, explain the reason for conducting the projects, the scope of digitized material, the criteria for its selection and how these projects benefitted the users in accessing the material. The aim of this paper is to clarify the benefits of digitized material and to establish existence or non-existence of a desire and need for further digitization. According to the implemented projects, the possibilities and frequency of digitization of museum publications will be researched in order to facilitate their availability and long-term protection of originals enabled by the creation of digital reviews.
