The Library owns approximately 1,800 editions published before 1831; just over half of these are part of the book collections listed below, and the rest were purchased from antique bookshops. The antique editions bear on subjects that are connected with economics in a wider sense: agriculture, commerce, dissertations on usury, demography, trade, numismatics and tax legislation. However, works of a more general nature are also to be found (historical, encyclopaedic, moral) along with rare and valuable editions of classical and modern literature.
The Library preserves collections of works originally belonging to personalities from the worlds of economics, politics and law; alongside these are homogeneous collections that testify to particular lines of interest that have developed over time within the Bank.
