The Digital Thesaurus portal is a result of works conducted within the project Sharing and digitalization of the 2D collections in The Historical Museum of the City of Kraków, co-financed by the European Union in the Malopolska Regional Operational Programme.
More than 18 800 exhibits, or artefacts as they have been called in recent years in museum nomenclature, were selected for digitalization within the framework of the project. Exhibits from three rich Museum collections were selected to be transferred into the „digital dimension”. The collections included: old photograph of Kraków, theatrical and graphic exhibits. The exhibits selected for digitalization represent about 20% of the collection of the Historical Museum of Kraków.
