The works of the Faculty of Philosophy and Faculty of Physical Education and Sports are the most represented. The collection of old and rare books consists of 400 monographic publications. Library users have a card, subject and electronic catalogue at their disposal. Publications not owned by the Library can be obtained through inter-library lending. In 2014, the Central Library of East Sarajevo became a member of the COBISS system. Consequently, we started processing books in a co-operative online bibliographic utility where the content of our library is available to the users. The department of technical and scientific book has the possibility of inter-library lending with other libraries from Bosnia and Herzegovina and the region.
