The library uses a simplified version of the Library of Congress classification system.
There are three main sequences: JL for politics, HC for economics and F for history. Each sequence is subdivided by country (indicated by a number) and by the surname of the first named author (first letter). For example, JL 950 R denotes JL (politics) 950 (number for Latin America in general) R (Rodriguez).
Books on politics and economics are shelved in the main library and seminar room on the first floor. The open-access stack on the ground floor houses history books, journals and books on labour relations and land reform.
Books not on open access will be fetched by staff on request.
