Nowadays, with the arrival of lifelong learning, a museum is expected to be an important social educational institution, and the demand for public information presentation, and educational activities has been increasing. In order to utilize effectively limited resources (personnel, equipment, money, etc.) and to offer the maximum service to users (the public, researchers, curators, staff, etc.), it is necessary to share information, to make a team and to advance activities efficiently. It is important that the librarian who works in a museum also grasps the demand of the users positively as an informational specialist and provides information.
