Inaccurate references hinder retrieval of documents, may prevent researchers from examining all of the work by an author, and may result in authors not getting credit for their work. This study determines the number and types of errors in references in four widely read pediatric nursing journals. Of the 190 references examined, 79 of them contained an error, for an overall error rate of 41.6%. Major errors, which prevent the rapid retrieval of information, occurred in 28.9% of the references. Minor errors occurred at half the rate (13.7%) of major errors. Errors in the titles of articles, chapters, and books were the most common type of mistake followed by errors in authors' names.
