New Headway Beginner is aimed at absolute beginners, or those who have learned a little English but lack the confidence to build on it. It provides a solid foundation for New Headway Elementary, and its measured, step-by-step approach builds both skills and confidence. The right mix of language work and plentiful practice material enables learners to consolidate their knowledge of key points before proceeding further. The clearly defined grammatical syllabus includes past, present and future time and provides a thorough basis on which to build. The presentation of new language is gradual, methodical and clearly structured, giving learners a clear sense of progression. The vocabulary syllabus focuses on high-frequency survival terms and avoids overload.
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.
