Can NIOD help me with my school project?
NIOD's image collection (with photos, drawings, and posters) can be consulted via the WWII Image bank website. Images can be downloaded directly from this site for educational purposes or private use, provided that they are not subject to copyright law.
A good starting point for your research into the Second World War is the Tweedewereldoorlog.nl portal. If you are looking for original sources from or about the Second World War, you can also use the Netwerk Oorlogsbronnen (the 'Dutch Network of War Collections') search engine.
