The documents of the Hungarian Institute of Public Administration, founded by professor Zoltán Magyary (1888–1945), an internationally renowned scholar of public administration, and Magyary's personal legacy were preserved by the Department of Public Administration Law of the Faculty of Political Science and Law of ELTE. In 2015 and 2017, ELTE and NKE concluded an agreement on the digitization and public publication of the legacy, as a result of which NKE handed over the digitized documents to the University Library and Archives in December 2023. 1 404 items can already be searched and researched in the ELTE Digital Institutional Knowledge Base, and the documents and maps will be managed by the University Archives from 2022.
