If you have to publish a journal we can help you to apply for an ISSN and DL
- The International Standard Serial Number (ISSN) is the internationally accepted unique identification number for periodical publications.
- The Dipòsit Legal (DL) classifies bibliographic output on a national level, assigning a number to each edition of a publication.
We also recommend adding a Digital Object Identifier (DOI) to journal articles. The DOI is a unique and permanent identifier for digital objects. You can request a DOI for articles in the UPF’s scientific journals and for other digital documents or objects.
