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 used to love that book ! We studied it at school in the English class of 2nd grade .. I even remember that I tried to imitate the recipes that Archie did ..The lollipops , the apples with caramel and the chocolate cookies .. But in the end I got a messed up kitchen and a heavy punishment :D Good memories !
I LOVED this little book. Because Mom, actually made us use the recipes in there and make our own lollipops!
Now what was his brother's name?? was it Arthur or Ronald?? *I can't really remember.. but 20 years later and I remember he had a brother.. pretty impressive in and out of itself.. eh?!
