The Honour Roll of the Fallen 1940-1945 was drawn up under the responsibility of the Netherlands Institute for War Documentation (NIOD). The institute is in charge of checking the reliability of the list and making alterations if necessary, also after the official presentation of the Honour Roll in 1960.

There are two aspects to this verification research. Data may turn out to be inaccurate and need to be altered. In addition the institute occasionally receives a request to add new names to the Honour Roll.

NIOD endeavours to make the Honour Roll as complete as possible. However, sometimes the far from perfect sources situation permits only limited verification. For example, it is not always possible to indicate the exact date and place of death.

In the past changes were made calligraphically on the document. Although this was always done with great care and expertise, it proved to be detrimental to the quality of the paper. NIOD has therefore decided to incorporate changes only in the digital Honour Roll as of 2009. Out of respect for the past, NIOD also presents the original, calligraphic text on the website.

NIOD has also seized this opportunity to correct, as far as possible, inaccuracies in the Honour Roll. As a result some of the digital text on this website is not identical to the calligraphied Honour Roll. Resistance fighters, servicemen, and crew members of merchant navy ships who died after 1945 and are on the Honour Roll, are no longer included in the digital Honour Roll. It concerns an estimated 3% of the total number of names.

The application form that was used in the past provided the opportunity to include a photograph of the person who died during the war. Several people did include one. These photographs will be added to the website at a later date.
