The ISSN Portal is a web-based interface available at http://portal.issn.org. The portal gives access to the ISSN Register, the international database which contains key identification information about print and digital journals, magazines, newspapers, newsletters, and scholarly blogs and Open Access scholarly resources published in more than 100 countries.

You can find and reuse standardized identification data for more than 1,8 million print titles and more than 200,000 digital titles. 60,000 new titles are added each year by our network of professional librarians. ISSN data is amended on a regular basis with more than 130,000 updates each year.

The ISSN Register is thus the most complete and international reference database for the identification of serial publications.
