I have always found this booklet most useful. Everything I have had problems with has always been answered within its covers, and it is a great quotable source for use with awkward authors.Editing Matters, Jul/Aug 2008The sixth edition ofUnits, Symbols and Abbreviations is an excellent guide for authors, scientists, medical writers, and editors. The authors present very good references throughout the book - I believe this book is an excellent companion for any author and editor in the field of biomedical sciences.(WAME) and Editorial Consultant, The Lancet, Jun 2008This little paperback is remarkably informative for its size. It is a quick reference source for anyone writing theses or papers and is very reasonably priced.Patricia de Winter, Physiology News 72, Autumn 2008
