Meditations is an inspiring, personal devotional booklet offering daily Scripture-based, soul-searching studies of God's Word. Each meditation is clearly written and easy to understand, with a special Scripture reading, devotion, and prayer for each day. Meditations provides scriptural guidance and encouragement for daily living.
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.
