Narodna Biblioteka Srbije

What Narodna Biblioteka Srbije does

The National Library of Serbia (Narodna Biblioteka Srbije) is a state-owned national library founded in 1832 and headquartered in Belgrade. It functions as the country's central bibliographic institution and the sole authorized issuer of ISBN, ISSN, ISMN, and CIP records for all Serbian publishers and serial publications. It serves as a UNESCO deposit library, holding copies of publications issued through the United Nations system, and maintains a physical collection exceeding six million library items, including rare manuscripts and cultural heritage materials.

Its core technical and service infrastructure includes the COBISS.SR library management network (the Serbian segment of the regional COBISS platform), a digital repository, the KoBSON consortium for licensed academic journal access, and multiple specialized reading rooms. The library also participates in international networks including LIBER, IFLA, and the recently adopted AI4LAM community. Publisher-facing services include formal contractual terms, price lists, and identifier issuance workflows.

The business model is primarily state-funded through the Serbian national budget, with supplementary revenue from publisher fees for bibliographic services, membership fees, reproduction and copying services, and event/exhibition income. Its customer base spans the general public (reading rooms and public access), academic researchers and students (KoBSON and research access), publishers (mandatory ISBN/ISSN/ISMN/CIP registration), and people with disabilities (specialized accessible services). The mandate is statutory and non-commercial, so revenue is not generated for profit or shareholder return.
