The Hungarica Documentation Department of the National Széchényi Library has developed a new web service with information on foreign libraries having Hungarica material (documents related to Hungary or written by Hungarian authors in Hungarian or other languages). The department also Issues a series entitled "Directory of foreign libraries holding Hungarica material" ("Hungarika-anyagot őrző külföldi könyvtárak címjegyzéke").
The possibility of appearing on internet was created by a Unesco-IFLA project. The main requirement concerning the planned system was to offer a variety of keys for browsing, and that it be bilingual (Hungarian and English). The input of data was based on text files compiled earlier of the manually organised paper documents. More recent and supplementary data were input in WinWord. Text files edited by Word 6 served as the bases for processing. SGML compatible markers were used.
Hungarica WWW can be accessed from the home page of the National Széchényi Library. It is possible to search by country and subject.
