Online corrections
​ The version of an article which is published online is considered the final and complete version. Even though it is possible to correct this version, our policy (in common with other publishers) is not to do so, except in very limited circumstances.
We can only fix typographical errors in the following words: names of authors, affiliations, titles of articles, abstracts and keywords. In such instances, an erratum or a corrigendum will also be required (see below) so that the discrepancy between online and print versions can be clarified in a record.
If there is a serious mistake, such as with regard to scientific accuracy, or if your credibility or that of the journal is affected, we can publish a correction to your paper. We do not publish corrections that do not materially impact the contribution or substantially damage the comprehension of the contribution by the reader (such as a spelling mistake or a grammatical error).
If you need to make any changes, please send an email to info@ijiest.in

Errata
An erratum will be used if an important error has been introduced during the production of the journal article (one that affects the publication record, the scientific integrity of the paper, the reputation of the authors or of the journal), including errors of omission such as failure to make factual proof corrections requested by authors within the deadline provided by the journal and within journal policy.
We do not publish errata for typing errors except where an apparently simple error is significant (for example, an incorrect unit).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 shall take advice from independent peer-reviewers and, in the text of the published edition, enforce the required modification, acknowledging the dissenting author(s).

Addenda
An addendum is a notification of a peer-reviewed addition of information to a paper in response to a request for clarification from a reader, for example. Addenda should not contradict the original publication, but if significant information available at the time was unintentionally omitted by the author, that material could be released as an addendum after peer review.
Addenda are published only occasionally and only if the editors conclude that the addendum is important to the comprehension of a substantial portion of the published contribution by the reader.
