Pioneer Research Group Journals

We do not publish errata for typing errors except where an apparently simple error is significant (for example, an incorrect unit). A significant error in a figure or table is corrected by publication of a new corrected figure or table as an erratum. The figure or table is republished only if the editor considers it necessary.

Corrigenda

A corrigendum is a notification of an important error made by the authors of the article. All authors must sign corrigenda submitted for publication.

In cases where co-authors disagree, the editors will take advice from independent peer-reviewers and impose the appropriate amendment, noting the dissenting author(s) in the text of the published version.

Addenda

An addendum is a notification of a peer-reviewed addition of information to a paper, for example in response to a reader's request for clarification. Addenda do not contradict the original publication, but if the author inadvertently omitted significant information available at the time, this material can be published as an addendum after peer review.

Addenda are published only rarely and only when the editors decide that the addendum is crucial to the reader's understanding of a significant part of the published contribution.
