Truly, all things do testify of him, Jesus Christ, the Savior and Redeemer of the world. Among the most magnificent testimonies of Jesus are the inspired and breathtaking paintings of Latter-day Saint artists. In All Things Testify Of Him, twenty-eight popular and talented :LDS artists present a portfolio of their work. More than one hundred of their paintings are reprinted in this full-color keepsake book.
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.
A large coffee table book (or, an herbal tea table book??) of artwork by many known and some lesser known artists of LDS influence. The pictures are large and satisfying, the book is sturdy, and the mood is one of celebration and spiritual regard for the subject matter.
