I stand by my suggestion to create tables of contents for volumes you put together for a specific student which are comprised of various pieces. Imagine how long it would take the student to find the correct pieces for study and rehearsal without that reference. I think we are justified in taking a small liberty from the Formats Guidelines if it would be of great assistance to the musician.
I think your proposed title page looks perfect. Your table of contents would then include all titles and composers (and arrangers if applicable). Specific copyright info can then follow each separate piece.
