For small to medium sized errors, the managing editor will review all corrections before they are published. However, in the case of larger scale errors, determined by whether they damage the credibility of the publication, harm individuals, or create a public backlash, the editor-in-chief will review the errors.
For the online mediums, a little block on the front page will list all the corrections that have been made, updated on a daily basis from most recent to oldest. For print mediums, the corrections will be posted on a portion of the page on a weekly to monthly basis. Each entry will identify the mistake that was made and the date it was altered or change.
Not only will the online publication cite the error, but in the original article where the error occurred, a brief sentence will explain, at the bottom of the article, what the error was, who committed it, when it was changed. The incorrect names, dates, or any general information that was missed will be included in the sentence.
Unless the error is minimal, such as missing periods, typos, grammatical mess ups like comma splices, most errors will be noted. But if it is not a glaring error and one that will not change the contents of the article, then it should not be listed as an error and not identified as a correction. The Ombudsman will be there to determine whether these errors are negligible or hurt the integrity of the reporting and writing that was done.
In the case of fabrication or plagiarism, the Ombudsman and editor-in-chief will conduct a thorough investigation and publish the results on the front page. On online, it will be featured as it's own article on the front page, but not taking up the majority of the space. On print, it will be noted on that top of the print version and lead to the story elsewhere in the paper.
