“Corrigendum” (plural “corrigenda”) originates from the Latin word “corrigere,” which means “bring into order.” In publishing, a corrigendum is an error, or a thing that should be corrected in some way — such as a misspelling or a punctuation error. Books go through a lengthy process to get to publication, part of which is distributing advance reader copies (ARCs). These promotional copies go out to bloggers, reviewers, and press in order to create some buzz, and they are a way for authors, editors, and publishers to evaluate the work for corrigenda before the book is finally published.
