When a book or article is not available in the Radboud University Library, you can request the publication via interlibrary loan (ILL). This is not for free. You need an ILL-account for this. Via PiCarta you can request the publication from another Dutch library.
Opening an ILL account is free of charge. However, when opening an ILL account via the webshop, a deposit of at least €1,- is obligatory.
It then takes two days at most before your account can be used. You receive an email when the amount is credited to your account.
The use of the requested materials is restricted to purposes of research and education only. Commercial use is explicitly prohibited.
