Much of the value of the "Dictionary" consists not only in the depth and detail of the individual articles, but in the copious and specific citations to individual Greek and Roman writers, as well as modern scholarship from the Renaissance to the mid-nineteenth century. The articles frequently note variant traditions, disagreements among the authorities, and the interpretations of modern scholars. However, due to the variable numbering systems used in different editions of classical works, and the difficulty of recognizing typographical errors in citations, the original sources should still be checked. Many of the "Dictionary's" articles have been referred to in more recent works, and Robert Graves has been accused of "lifting his impressive-looking source references straight, and unchecked" from it when writing "The Greek Myths".
