FAQs – ISSN

What is ISSN?

ISSN (abbreviation for International Standard Serial Number) is an eight-digit numeric code used to identify the title of a serial publication in the International ISSN Portal. You can find out more about ISSN here.

What is a serial publication?

It is a publication that is published under one title on any medium without a predetermined end date. It is published in parts, usually with a numerical or chronological designation (the exact definition is given in ISO 3297). ISSNs can be assigned to serial publications regardless of the period in which they were, are or will be published. The term includes not only periodicals – newspapers, journals, but also yearbooks, annual reports, proceedings, editorial series, etc.

Some issues have an X at the end. Isn’t that a mistake?

It is not a mistake. The last digit of the code is a check digit. If the result of calculating the check digit is ten, the Arabic 10 is replaced by a Roman X to maintain the eight-digit range of the code.

Can I use the same ISSN if I change the name of the journal?

If the title of a journal changes, the publisher is required to report the change in advance to the ISSN Centre and request an ISSN for the new title. Only minor changes in the title do not affect the ISSN and will be entered in the ISSN record as a so-called variant title.

Is it necessary to apply for a new ISSN if the publisher, its location, the periodicity of the periodical, etc. changes, but the title remains the same?

No, but the National ISSN Centre (NC ISSN) should be informed of the change (by email to issn@techlib.cz or by phone).

Is the ISSN also assigned to electronic publications?

Yes. ISSNs are assigned to electronic publications if they are serial publications or other so-called continuing resources (online journals, websites, etc.). However, commercial sites, personal blogs and websites, sites linking to other sites and some other types of sites are not assigned an ISSN.

I used to publish a paper journal, but I’m moving its publication to the Internet. Can I use the number of the print title?

No. You need to apply for an ISSN for the electronic version of the journal.

Is it possible to apply for an ISSN before the 1st issue is published?

Yes. The publisher must submit an application and a preview of the journal cover, title page, and masthead to the NC ISSN.

Who can apply for an ISSN?

The publisher or a person authorised by the publisher applies for an ISSN. A library can also apply for an ISSN.

Where should the ISSN be located?

On the first page of the cover, on the title page, or in the front matter. If a publication is identified by an ISSN and an ISBN at the same time, both should be given.

How much does it cost to assign an ISSN?

The allocation of an ISSN is free of charge.

How to get an ISSN for printed continuing resources?

  • It is published periodically under the same title with no predetermined end date.
