+ <h2 id="Corrections and retractions">Corrections and retractions</h3>
+ <p>
+ SciPost pursues the following policy for making corrections to its peer-reviewed content:
+ </p>
+ <ul>
+ <li><strong>Modification of a paper</strong>: SciPost reserves the right to replace a published paper if purely technical corrections are necessary (e.g. corrupt file or incorrect bibliographical entry). In such cases, archives and indices are informed. Under no circumstances will the content be changed.</li>
+ <li><strong>Corrigendum</strong>: notification of an important error made by the author(s) or by the journal that affects the publication record or the scientific integrity of the published, peer-reviewed work or the reputation of the author or the journal. Corrigenda are represented by a formal online notice.</li>
+ <li><strong>Retraction</strong>: authors or, in specific cases, SciPost can decide to formally withdraw a published journal article. The article stays online but the reader is notified about the retraction. Such retractions are most often accompanied by an editorial note explaining the background.</li>
+ <li><strong>Marked as fraud</strong>: in the unlikely case that SciPost is notified that a published journal article turns out to be a fraud, the paper stays online but is formally withdrawn. The reader is notified about the status and fraud papers are always accompanied by an editorial note pointing out the malpractice.</li>
+ </ul>
+ <p>All corrections and retractions can be traced through our participation in Crossref's <a href="https://www.crossref.org/services/crossmark/">Crossmark</a> service, as detailed on our <a href="{% url 'journals:crossmark_policy' %}">Crossmark Policy Page</a>.</p>
