The Ultimate Visual Dictionary 2001. No author listed - ISBN: 0789461110 according to Amazon.com. You look up the subject in the index, go to the page, and look at the picture with all the parts identified. There's over 6,000 full color pictures in the book. The hard cover edition will break your foot if you drop it. In general, I like the Howdunnit series for mystery writing, but some of the books work well cross-genre: Deadly Doses - A Writer's guide to Poisons by Serita Stevens and Anne Klarner. (It includes historically used poisons as well as modern ones.) Body Trauma - A Writer's Guide to Wounds and Injuries by David W. Page. (I'm very sqeamish, so I'm very slowly making my way through this book.) It gives a good idea of what someone can and can not do given a specific injury. It's written for modern times, but it can be used for any genre. Currently, I'm looking for a good historical reference book on medieval life in various countries. The one that I bought sucketh. What have y'all found?
