Some researchers state that the core functions of art galleries are different from those of art museums. Galleries are related to the art market for the purpose of selling artworks, whereas museums are agents of culture, impart art education and conserves the works of Old Masters and the most representative works of contemporary artists (Zukin: 428). On the other hand, Duncan (p.1) asserts that in the United States the terms art gallery and museum of art are used interchangeably, and it is only in Great Britain that there is a distinction between the two terms.
There are several daily tasks and aims of art galleries and museums: An important task is organizing museum-school participation: Museum educators develop and carry out several levels of art education programs for school children. These are interactive, informative and teach art appreciation and history, through multi-disciplinary programs. (Zeller: 51. Stone: 83). Art-works help in the protection of the human environment: The natural and human environment as perceived by the creative artist is depicted in both historical and contemporary artworks (Riviere: 34). The environment keeps changing with time, as populations increase, the power of technology and built environment advance further. The earlier environments and spaces which are captured by artists thus serve to refresh viewers’ memories and take them back in time.
Art galleries also help in building community through art experiences: “Societal structures like family and community need all the help they can get”, states Arnold (p.47). To strengthen communities, to increase a feeling of unity and belonging among students, to build ideals of commitment and responsibility.
