ISSN in printed periodicals

Please print the ISSN in the same prominent position on the outer cover (and, if possible, on the imprint page) of every issue, volume, year etc. It must be preceded by the letters “ISSN” as in the following example: ISSN 1234-5678.

Note: The last digit is a check digit; it is represented by an “X” if its numerical value is 10.

It is up to you to decide which typography to use.
