In addition to printed media units, the OPAC also catalogues electronic media, audiovisual media, almost 800 printed journals and numerous electronic journals. Open access publications that match the collection profile are also catalogued.
Thematic searches are possible in the catalogue using keywords. Subject-specific articles from anthologies and journals are continuously indexed and can be searched in the catalogue - now over 30,000 articles.
The print holdings are catalogued in the library's reading rooms by consecutive number (numerus currens). Digital holdings can be viewed on site.
