Literature that is not available in Hamburg can be requested online via the GVK - GBV Union Catalogue (Gemeinsamer Verbundkatalog, GVK). Then you can use interlibrary loan.
Detailed information about interlibrary loan (in German only) can be found on the website of Universität Hamburg library system and under the interlibrary loan information at the information center in the State and University Library (Stabi).
The book you need would be a good addition to the specialized collection of the Business, Economics and Social Sciences Library?
Then send us your purchase request (in German only).
