(Fred Bock Publications). The perfect gift for honoring the person in your life who is a musician and lover of great hymns. Most of the arrangements for congregational singing feature a bright introduction, interlude with modulation leading to a re-harmonization. This collection also contains pictures depicting the Cathedral organ's rich history.
Various is the correct author for any book with multiple unknown authors, and is acceptable for books with multiple known authors, especially if not all are known or the list is very long (over 50).
If an editor is known, however, Various is not necessary. List the name of the editor as the primary author (with role "editor"). Contributing authors' names follow it.
Note: WorldCat is an excellent resource for finding author information and contents of anthologies.
