+universal library system for facilities in the university. Currently hard-coded for the Library of the University of Education in Freiburg, Germany, but can be adapted to fit other libraries as long as the catalogue has a suitable format, or an open API
 
 Other Libraries can be supported by rewriting the catalog and it's corresponding functions.
