ISBN, ISSN and DOI are tools that make your publications visible and easy to cite in the world.

ISBN is a universal international book number that identifies each edition of a book or monograph.

ISSN is an international standard serial number that officially registers a journal or collection and confirms its status in the scientific community.

Instead, a DOI is a unique digital identifier for each individual article, book, or chapter that guarantees the permanence of the reference regardless of changes to the website or archive.

We help you to:

• obtain ISSN for collections, journals, periodicals;

• register DOI for individual articles, books or chapters;

• get ISBNs for your individual books or different editions;

• prepare the necessary documents and supporting materials;

• explain how to properly use identifiers in publications.

ISSN, ISSN and DOI are not a formality, but tools that open the way for your work to an international audience and strengthen your academic reputation.
