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.
I have the 1976 edition, which my Father gave me in 1977 for my 16th birthday. This Bible came to Africa with me and has served me well for many years. I have read it through many times. I estimate my first time to read it through was around 1979.
