One of the more useful types of study notes in The Wesley Study Bible are little boxes called "Wesleyan Core Terms." Some core terms covered are: Holiness, Discipline, Faith, Doctrine, etc. There is a handy index in the back of the Bible, which gives page numbers for the core terms, both in alphabetical order and in biblical order.
The rest of the study notes are pretty typical of more liberal study Bibles, such as the HarperCollins or the Oxford Annotated. There are some "Life Application Topics," which are reminiscent of some of the notes in the popular Life Application Study Bible, which is available in a variety of versions. As I greatly prefer the NRSV to the CEB, I don't expect that I'll ever acquire a copy of the CEB version.
As I have served as a Director of Music in Methodist churches for almost two decades, and now self-identify as a United Methodist, I have found this study Bible to be a useful resource, one which I have not spent enough time with.
