If in the Aladí catalog you find a document that is not in your library, you can ask the staff of the library to reach you through the interlibrary loan. Thanks to this service you have at your disposal the fund of more than 228 libraries and 12 libraries of the Municipal Libraries Network.
You can also request by interlibrary loan the fund of the rest of the public libraries of Catalonia and the Goethe-Institut. This service has no cost.
The PI with Catalan public universities will depend on each library. The price is established according to the regulations of the institution that owns the document.
