The field of research of museology includes: a) the study of the history and theory of collections and the rules of evaluating artefacts and collections, b) how museums’ scientific and social background should be studied as a living organism, c) the study of other sciences relevant to museums, such as history of art and how such sciences affect today’s museums, and d) the study of museums’ relationship with society and the various social groups they serve. This last function of museology touches on sensitive matters such as how a museum should present such things as ethnic minorities, different historical memories, how different identities are shaped and so on.
