As part of the University of Cologne, the Faculty of Management, Economics and Social Sciences holds a large collection of subject-specific literature and journals. The most comprehensive collection can be found at the University and City Library of Cologne. Via this link as well as by means of the Kölner Universitäts-Gesamtkatalog (University of Cologne Central Library Catalogue) you can order specialist books and journals or have them sent and lended by other associated libraries nationwide.
For borrowing books a library card is required which is obtainable from the library staff. Additionally, the University and City Library of Cologne offers introductory courses.
