I also wrote an article about the book for Locus Online which features lists of most frequently quoted works, most frequently quoted authors, and most popular topics. However, I limited the lists to the top fifteen in each category. Presented here for the first time are the complete versions of the lists I compiled, with all works that were quoted at least ten times, all authors who were quoted at least 15 times, and all topics that included at least 25 quotations.
