Many of the editions by this group of authors are actually guides to books rather than the works.
If the author of the SparkNotes is known, they should be the first author. Please leave these SparkNotes Editors as the second author and the author of the original work as the last author. Do not combine with the original work. Do not put the author of the ORIGINAL work first.
I use this book when teaching and tutoring test-prep courses (and not just the SAT), as well as reading, writing, math, and statistics courses. It's an excellent resource, especially when used in conjunction with the Sparksnotes.com website.
