newspapers, journals, magazines and periodicals of all kinds and on all media–print and electronic.</p> <ul> <li>Which publications are concerned by an ISSN?</li> <li>What form does an ISSN take?</li> <li>What is its role?</li> <li>Where is it displayed?</li> </ul> <h2>Which publications are concerned by an ISSN?</h2> <p>An ISSN (International Standard Serial Number) identifies all continuing resources, irrespective of their medium (print or electronic):</p> <ul> <li>newspapers,</li> <li>annual publications (reports, directories, lists, etc.),</li> <li>journals,</li> <li>magazines,</li> <li>collections,</li> <li>websites,</li> <li>databases,</li> <li>blogs,etc.</li> </ul> <p>In many countries, an ISSN is mandatory for all publications subject to the legal deposit.</p> <h2>What form does an ISSN take?</h2> <p>The ISSN takes the form of the acronym ISSN followed by two groups of four digits, separated by a hyphen. The eighth digit is a check digit calculated according to a modulus 11 algorithm on the basis of the 7 preceding digits; this eighth control digit may be an “X” if the result of the computing is equal to “10”, in order to avoid any ambiguity.</p> <p>e. g.:</p> <ul> <li>ISSN 0317-8471</li> <li>ISSN 1050-124X</li> </ul> <h2>What is its role?</h2> <p>The ISSN role is to identify a publication.</p> <p>It is a digital code without any intrinsic meaning:</p> <ul> <li>it does not include any information about the origin or contents of the publication,</li> <li>it does not guarantee the quality or validity of the contents.</li> </ul> <p>The ISSN is associated with the title of the publication. If the publication is modified significantly, a new ISSN must be assigned.</p> <h2>Where is it displayed?</h2> <p>For a <strong>print publication</strong>, the ISSN should be shown:</p> <ul> <li>preferably, in the upper right corner of the cover,</li> <li>failing that, on the pages where editorial information is shown (publisher, frequency, colophon, etc.).</li> </ul> <p>For a <strong>publication in electronic media</strong>, the ISSN should be shown:</p> <ul> <li>on the homepage or on the main menu, if it is an online publication,</li> </ul> <ul> <li>on any part visible to the naked eye (microfiche header, CD-Rom or DVD label, box, case, etc.), if the publication is on a physical medium.</li> </ul> <p>If a publication is identified by ISSN and ISBN, both of these identifiers should be mentioned.</p> <div class="encadre"> <p><strong>A few definitions</strong><br /> <strong>• Continuing resources</strong>: a continuing resource is a resource, on any medium, that is published over time without a predetermined end.<br /> Serial publications and ongoing integrating resources are continuing resources.<br /> They are defined by the ISO 3297 standard.<br /> <strong>• Serial publication</strong>: a serial publication is an unfinished set of documents, published successively under the same title, for an undetermined period of time.<br /> The ISO 3297 standard defines it as a publication, in any medium, issued in successive parts, usually having numerical or chronological designations, that has no predetermined end.<br /> <strong>• Ongoing integrating resource:</strong> an ongoing integrating resource is a non-fixed resource. It can be updated at any time by adding information or by replacing obsolete information with new information.<br /> It is defined by ISO 3297 as a continuing resource that is completed by updates integrated into the body of the work.<br /> <a title="The ISSN for electronic media" href="https://www.issn.org/understanding-the-issn/assignment-rules/the-issn-for-electronic-media/?lang=en">Click
