The Inter-Parliamentary Union (IPU), on the basis of official information provided by national parliaments, provides three free databases with bibliographic references (no abstracts) on books and articles dealing with relevant topics related to parliaments and legislatures. Parlit is a database with references on national parliaments, electoral systems, constitutional law, history and political science, parliamentary law and legislative elections throughout the world. Over 7,000 books and studies as well as 30,000 articles taken from 160 periodicals are indexed but the database is no longer updated after 2002. Two other IPU databases – regularly updated – are Parline and “Women in Politics”. The first provides general information on each parliament’s chambers, description of the electoral system, results of the most recent elections, information on the presidency of each Chamber and on the mandate and status of MPs. The latter gives bibliographic references on books and articles dealing with women’s participation in political life. Links to parliaments worldwide and to topic-related websites are also available for each database.
