This guide to the essentials of bathroom etiquette takes in more than just remembering where to put the toilet paper and which seat position is correct - - it's a guide for the whole man, taking in top-to-toe grooming and care essentials. Everything is examined from which medicines to store in the bathroom cabinet, to masculine-but-effective beauty treatments and even how to unblock a toilet and make sure it stays that way. This is the book for anyone wanting to banish those unpleasant odours from their bathroom and their person, with clear and effective advice as well as cunning tips for making the bathroom the best room to relax in.
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.
