INTRODUCTION The practice of citing previously published work to support current investigations is one of the foundations of medical literature. It places an article in a context, builds on prior work, establishes credibility, and leads readers to additional resources on the topic. According to the Uniform Requirements for Manuscripts Submitted to Biomedical Journals, “Readers should … be provided with direct references to original research sources wherever possible” . Peer review and editing guarantee the accuracy and relevancy of the scientific information presented in a paper, and the same measures should be applied to the references (also referred to in this paper as “citations”). Unfortunately, as demonstrated in reference accuracy studies, including studies done in major medical publications, verification of reference accuracy is not taking place in many journals.
