This first book of questions and answers covers key subject areas such as history, natural history, space and science. The fun questions are clearly answered and fantastic illustrations help explain things further. Throughout there are cartoons to keep kids hooked and some extraordinary facts to really entertain young minds. Specially designed parent panels give tips on further learning, and a fun quiz at the back of each section tests children on what they have read.
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.
