Every now and again a paper is published on the number of errors made in academic articles. These papers document the frequency of conceptual errors, factual errors, errors in abstracts, errors in quotations, and errors in reference lists. James Hartley reports that the data are alarming, but suggests a possible way of reducing them. Perhaps in future there might be a single computer program that matches references in the text with correct (pre-stored) references as one writes the text.
