If you have a simple question, for instance about the availability of certain collections or documents, NIOD prefers to be contacted by telephone. In that case, you will learn straight away whether it is worth your while to visit us or whether you should send us your question in writing. More extensive and substantive questions can be submitted through the contact form. Before contacting the Institute, we recommend consulting the Frequently Asked Questions section of our website, which contains quick answers to many questions.
Questions submitted to the institute in writing can sometimes be answered by referring you to the institute's reading room or to another institute. If a request leads to an extensive and time-consuming investigation, a fee may be charged. You will be informed about this in advance. Generally speaking, not all questions can be answered since not all archives have been preserved in their entirety.

The image collection of the NIOD (including photographs, drawings, and posters) can be consulted via the WWII Image database. Images (provided they are free of rights) can be downloaded directly from this site for educational purposes or private use.
A good website to start research on the Second World War is the portal Tweedewereldoorlog.nl.
To search for original sources from or about the Second World War, you can also use the search engine of Netwerk Oorlogsbronnen.

Do you have a question about our collection, library, archives, or ongoing research? Various NIOD staff members are happy to assist you with their specific expertise.
