When a greeting card isn't enough, these greeting books really shine. The colorful hardback covers carry greeting card sentiments, but inside are forty pages of stories, quotations, Scriptures, and more - all to express your feelings at an affordable price. In fact, the price of thes e books is less than many greeting cards, and free envelopes are provided for mailing.
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.
