An erratum is a notice issued by a publisher or author to correct errors in a previously published scientific or academic work. This can include errors in calculations, typos, incorrect data, or other inaccuracies that may have been overlooked during the peer review process. Errata are typically published as a separate document or as a note in the publication where the errors occurred, and they serve to ensure the accuracy and integrity of scientific research. Researchers are encouraged to carefully review and acknowledge errata to prevent the spread of incorrect information in the academic community.
