The NAL is a member of the International Federation of Library Associations and Institutions and actively participates in its annual conference, WLIC. The NAL joins in three sections as standing committee members: Library and Research Services for Parliaments Section, Government Information and Official Publication Section, and Asia and Oceania Section. The NAL works with other parliamentary libraries around the world:
To assist in the development of parliamentary libraries by providing assistance and support in accordance with the interest, requirements, and stage of development of parliaments in various regions of the world; to encourage bilateral assistance and development programs; and to act as a clearing house in this regard;
To encourage programs which foster the adaptation of the latest information technologies to parliamentary library services;
To examine the relationship of the research work carried out in parliament and by public and private institutions and the needs and work of parliament with special reference to the library and research services of parliaments themselves;
To examine the administrative arrangements within parliaments with regard to library, information, and research services;
To strengthen the cooperation between the Inter-Parliamentary Union and parliamentary libraries, and explore possibilities of joint programs and activities;
To encourage the establishment of regional groups of parliamentary libraries like the European Center for Parliamentary Research and Documentation. A particular aspect of the Section's work is to promote cooperation between legislatures and especially their libraries because of the growing need for legislators to be well informed concerning developments worldwide.
