The museum is a cultural institution dedicated to the preservation and exhibition of a museum objects of artistic, cultural, historical, traditional, and scientific significance. Therefore, the museum represents a reliable source of knowledge and information whose resources are important elements for learning, and which are accessed and actively used by scientists and the public. The aim of this paper is to explore how a museum can be a reliable source of information, considering the context in which the information is presented. The paper deals with the research of the very concept of information, information science and the development of museology as a scientific discipline within this field of social science. The purpose of the paper is to explore the museum as an institution that is responsible for collecting, preserving, and interpreting a wide range of information about art, history, science, and culture. This information is often presented to the public through exhibitions, educational programs, and internet resources. In the context of museums, information science is often used to refer to the use of data management technology and techniques to support the work of museums, including collection management, digital preservation, and online access to museum collections. Accordingly, the paper explores the museological activity of the Museum Documentation Center. Information in museums can include a wide range of categories including objects in collections as well as documentation and metadata or information about the history, cultural context and condition of objects and information about their acquisition, preservation, and exhibition to the public.
