The Integrated Archival Information System, ZoSIA, was created by the National Digital Archives in Warsaw as a unified platform for archival description and access, based on such international standards. The system is being developed (along with an information technology IT infrastructure) since 2007 and nowadays is the main archival data management tool used by the Polish Archives. The ZoSIA provides both a way to record descriptive information about archival holdings and a means to view, search, and browse that information. It used also as a tool for creating finding aids. The introduction of the ZoSIA affected archival practice, as well as reference services. The change was accelerated by the technology development and the appearance of electronic records. In 2016, the Central Committee for Archival Methodology made a conscious effort to adjust the process of establishing intellectual control over records through to the usage of Integrated Archival Information System.
