The Institute collects primary source materials such as manuscripts, diaries, correspondence and photographs, as well as rare books, pamphlets and serials. We usually do not collect press clippings or copies of documents readily available elsewhere.
Why deposit your material at the IISH?
The IISH is the most renowned institute in the world in the field of socio-economic history. Our collections extend over 50 kilometers of shelf length. They are used by more than six thousand researchers a year for their research. The world-renowned collection was created by carefully acquiring and selecting from 1935 on, in the Netherlands, Europe and later at a global scale.
The IISH provides a safe haven for archives and other sources that socio-economic historians might want to use for their research. What we accept, remains in principle preserved forever, or at least as long as the institute exists. This makes the material part of the memory of the world. Organizations and people who deposit material with us make it available for historical research. This way, their thoughts, deeds and actions are given a place in history and do not fall into oblivion.
