In my library, I have over 500 books on hermeneutics and exegesis - textbooks, reference works, applied studies. In those books are over 900 references to my standard test pericope (Mark 1:1-8). These include references to text structure, imagery, typology, etc. that is rarely the emphasis of commentaries. I suggest that a section be added to Bible reference guides that searches these resources for Bible references and presents them to the user in a manner somewhere between the parallel Grammar section and the closely related Commentary section.
