  • Copy ordering

    Ordering of journal articles

    Copies of articles may be obtained directly via the ZDB-OPAC. Please check firstly the availability of a specific article in a library of your hometown. In such cases an interlibrary loan will not be executed. The document delivery service Subito will still accept your order but will charge much higher fees than the conventional ILL service.

    What is the difference between interlibrary loan and the document delivery service Subito?

    1. Interlibrary Loan (ILL)

    Only registered users of a library can place interlibrary loan orders. Your regional library or the electronic interlibrary loan system decides which library will be asked for the missing media. You will not become a client of another library. Your own library account will be charged with the respective service fee.

    2. Document Delivery Service Subito,

    Anyone can use this service following online registration. After submitting an order, a list of libraries that own the desired resource is displayed . You may then select a library and will become a direct customer of this library.
