"Sparknotes.com provides free access to online study guides in the areas of literature, the arts and sciences. While Sparknotes began as a site offering guides to literary classics (featuring summaries, plot analysis, character lists, themes and motifs, á la Cliff Notes), the collection has grown to include subject areas like health, nutrition, computer science, and biography. Major works can be sorted by author or title. Information about how to cite Sparknotes is also readily available on the site. A recent addition is an online test preparation area. While Sparknotes also offers the guides in print format to those who wish to purchase them from Barnes and Noble, the majority of the information is free, and Sparknotes.com is easy to navigate making it an excellent web site for students and researchers alike"--"Best Free Reference Web Sites 2004."
