The material collected in ADS can be downloaded after the former registration made on the Archive website. It involves completing a short form. Then a special login and password are sent to the users via e-mail. They allow for a free download of the whole technical and methodological documentation collected in ADS resources and attached to the data sets as well as the access to those resources the distribution of which was not restricted by the producers.
The access to the restricted resources is only available to these institutions that have signed an agreement of co-operation with the Archive.
Individuals and institutions that do not have a relevant agreement may turn to the Archive with a request for rendering the access to particular resources.
