The Canadian Library Association serves Canada and there are provincial associations as well, such as the Ontario Library Association. In the United Kingdom, the professional body for Librarians is the Chartered Institute of Library and Information Professionals (formerly known as the Library Association). The International Federation of Library Associations and Institutions (IFLA) represents the interests of libraries and librarians internationally. (See also the List of Library Associations.)
