A New Systematic Theology of the Christian Faith by Robert Reymond is a great systematic theology textbook which is very useful. However, the Logos edition of this book does NOT contain virtually any tagging - Bible verses, references to other books, etc. It does have a few hyperlinks that bring you to other places within the book, and links to the Westminster Confession of Faith, but otherwise not the usual tagging.
The description page has the usual "In the Logos edition, this digital volume is enhanced by amazing functionality. Citations link directly..." except that it doesn't.
Is the missing tagging just an oversight?
