In 1945, shortly after liberation, the Netherlands founded the Netherlands Institute for War Documentation, the precursor to NIOD, with funding from the Ministry of Education, Culture, and Science.  Today, NIOD administers the archives of the German occupation of the Netherlands and the Japanese occupation of the Dutch East Indies and provides information to government agencies and private individuals.  NIOD also carries out a wide range of research projects dealing with the social and political aspects of WWII.  The National Archives and municipal archives, particularly of Amsterdam, are important sources of documentation.  A government-sponsored research institution, Network War Sources, works to improve digital access to the Dutch collection on WWII and the Holocaust through a web portal, which helps users navigate fragmented sources from more than 430 institutions.  The government also sponsors the Anne Frank Foundation, which, in addition to its many activities, conducts research.  The Netherlands financially supports and participates in the Arolsen Archives (formerly called the International Tracing Service), which include 30 million Nazi documents and documentation related to approximately 17.5 million victims.  The United States Holocaust Memorial Museum reports excellent cooperation with archives in the Netherlands and engages closely with the Netherlands through the Arolsen Archives.
