The National Bank of Belgium has a documentation base that is mainly specialised in economics, finance and monetary policy.
The collection includes over 100,000 books and about 1,300 periodicals. In its specialist areas, it is one of the largest historical collections in Belgium.
The whole of the reference works of the documentation base are included in the catalogue of the KU Leuven's Libis-Net network, which comprises the collections of the university itself and of other institutions such as the federal Parliament and the Ministry of Finance.
The consultation of the works belonging to the Bank's holdings is exclusively possible through the interlibrary loan.
