What Hochschulbibliothekszentrum does
Hochschulbibliothekszentrum des Landes Nordrhein-Westfalen (hbz) is a public-law institution (Einrichtung des öffentlichen Rechts) of the German federal state of North Rhine-Westphalia, headquartered in Cologne at Jülicher Straße 6. Founded in 1973 and operating with 51-100 employees, hbz functions as the centralized library service center for all universities and Kunsthochschulen in NRW, delivering shared technology, metadata, and digital infrastructure under the supervision and funding of the Ministerium für Kultur und Wissenschaft des Landes NRW. Its mandate includes serving as the Leihverkehrszentrale (interlibrary-loan center) for the NRW region, and its council (hbz-Rat) comprises representatives from every NRW university, embedding the institution in member governance.
hbz operates a multi-module technology platform organized into five service areas: library management and support (Systeme und Support, Lizenzmanagement, Bibliotheksstatistik); metadata services (Verbunddaten, Normdatenmanagement, lobid-organisations, GND-Reconciliation-Service, Knowledge Bases, Regionalbibliographien); digital collections and preservation (Digitales Archiv NRW, Webarchivierung, Digitalisierung, Landesportal NOAH); portals and interlibrary loan (DigiBib, DigiBib IntrOX, DigiAuskunft, Fernleihe, ELi:SA); and scholarly publishing infrastructure (OJS/OMP hosting, DOI-Konsortium NRW via DataCite, Langzeitverfügbarkeit LZV.nrw, Open Educational Resources including OERSI). The technical backbone includes the hbz-Verbundkatalog (a union catalog spanning more than 125 libraries in NRW and Rhineland-Palatinate), adherence to semantic web and library standards (GND, OAI-PMH, ORCID), and an open-source-first stack anchored on PKP's OJS/OMP. Notable integrations include DataCite, Google Scholar, DOAJ, Scopus, Web of Science, Sherpa/Romeo, and DNB Pflichtexemplar workflows.
hbz is funded by state appropriations and provides its core services free of charge to state-funded NRW universities through cooperative arrangements under the openaccess.nrw Landesinitiative (guaranteed through at least December 31, 2025). The institution does not generate commercial revenue from end users; instead, it monetizes through managed-services budget allocations. Go-to-market is sales-led via direct relationships with university libraries and the hbz-Rat governance structure, with outreach through the SWIB conference, newsletters, GitHub, and the hbz service wiki. Key strategic partnerships include Deutsche Nationalbibliothek (GND infrastructure), TIB - Technische Informationsbibliothek (OERSI), and the openaccess.nrw state initiative. Leadership comprises Dr. Silke Schomburg as Director (Leiterin), with an hbz-Rat Vorstand chaired by Dr. Jochen Johannsen (RWTH Aachen) and deputized by Sabine Boccalini (Universität Siegen).

Hochschulbibliothekszentrum competitors and assessment
Company assessmentOthers
- DataCite: DataCite is the DOI registration agency that powers hbz's DOI-Konsortium NRW. It is an ecosystem enabler whose continued operation is critical to hbz's persistent-identifier service.
- Public Library Karlsruhe: While a public library rather than a service center, it represents one of the institutional library users in the broader hbz ecosystem and adjacent cooperative library infrastructure in Germany.
Direct peers
- Bibliotheksverbund Bayern (BVB): BVB operates the union catalog and library infrastructure for academic libraries in Bavaria, offering a directly comparable service portfolio to hbz's union catalog, metadata, and Open Access offerings.
- HeBIS (Hessisches BibliotheksInformationsSystem): HeBIS is the Hessian library information system, providing union catalog and library services for academic libraries in Hesse — a state-level peer with a very similar service mandate to hbz.
- Verbundzentrale des GBV (VZG): VZG is the central service office of the Gemeinsamer Bibliotheksverbund, providing union cataloging, library systems, and Open Access services for libraries in Lower Saxony, Saxony-Anhalt, Thuringia, Hamburg, Bremen, Mecklenburg-Vorpommern, and Schleswig-Holstein — a direct structural peer to hbz.
- Bibliotheksservice-Zentrum Baden-Württemberg (BSZ): BSZ is the regional library service center for Baden-Württemberg, operating a union catalog, library management systems, and Open Access infrastructure — the direct functional counterpart to hbz for universities in another German state.
Broad incumbents
- Deutsche Nationalbibliothek (DNB): DNB is Germany's national library and the operator of the GND authority file. hbz and DNB are MoU-level co-development partners on GND infrastructure, making DNB both an enabling incumbent and a deep collaborator.
- TIB – Leibniz-Informationszentrum Technik und Naturwissenschaften: TIB is a national Leibniz information center for science and technology and a strategic co-development partner of hbz on OERSI. It operates overlapping research-data and Open Access infrastructure with a broader national mandate.
Regional players
- SLUB (Sächsische Landesbibliothek – Staats- und Universitätsbibliothek Dresden): SLUB combines a state library and university library in Saxony with its own digital and Open Access services. It is a regional peer with comparable infrastructure ambitions, though within the GBV rather than the hbz cooperative.
Emerging players
- Open Library of Humanities (OLH): OLH is a Diamond Open Access publisher using OJS infrastructure similar to what hbz hosts. It represents an emerging adjacent player in the Diamond OA space that intersects with hbz's hosting and infrastructure interests.
