Image & Sound

Image and Sound Collections held by the IISH include some 250.000 photographs and 120.000 posters - one of the largest collections of posters in the Netherlands. The Institute stores several hundred banners from the labour movement. In adddition, the collections include a considerable amount of films and videos, several thousand sound tapes and gramophone records. Check the menu for more information on specific materials.


The Image and Sound collections are accessible through the IISH catalogue and can be searched by organization, date, location or subject. There is a subject index in the thesaurus (see below). The catalogue shows digitized copies (low resolution scans only) of visual documents. In most cases it is possible to order reproductions, borrow materials for exhibitions or view the originals in the Reading Room. For rates, conditions and facilities, please go to Services.

NB Due to copyright claims in 2014 we have been forced temporarily to restrict access to previews of images through our catalogue. As a result, you will find thumbnails stating ‘Access to this resource is closed’ instead of low-resolution previews. As yet we are unable to say when we can grant access to (some of the) digital visual materials at again. The metadata records that describe the visual material are accessible.
When you consult the catalogue in the reading room of the IISH, it is possible to view previews of images.
