The Librarian must have the knowledge of various areas and they must have a source of public information. They must follow the trends of computers, media and trends related to publishing. The Librarian must have to manage the staff, program of direct information and develop public system. The Librarian must be focused on three aspects of work in their fields such as technical services, administrative services and user services. The librarians, who are in the user services, like as in children's librarians and references and help them to find the information about their needs. Their job is analyzing user needs to check what they are searching for and what they acquire; then the librarians provide them the required information.
An instructional role is another part of the job. This defines the librarian to show the user to evaluate and find the information. Such as users navigate the Internet by the librarian's advice and they will find the search for and evaluate information efficiently.
