Digital Products

Subscriptions to journals. It is possible to subscribe to the digital versions (PDF) of the journals. Subscription to the current volume allows you to immediately access the already published issues of the journal, which are available in the private area on the website. Next issues will be available on the website before print (subscribe to the mailing list on the site in order to be alerted to the on-line publication).

N.B. Volumes are partially independent of calendar year. Volumes are considered complete upon publication of the last issue of the volume itself, independently of the calendar year in which the publication actually occurs.

Separate (back) issues, back volumes and single articles are available in PDF beginning from volume 1993.
