Who runs a topotheque? The principles of the topotheque are: The access to historically relevant material should be freely accessible for interested people and the public. The handling of the provided material and their respective data must be trustworthy. This is why a topotheque should only be managed by an institution that doesn´t have any commercial exploitation of the historic material in mind and which is why mainly public institutions like communities, associations or education facilities manage a topotheque. It is these institutions that the population can place their trust in and therewith encourage private persons to allow public insight into private material.
