Volume two only. Like new, excellent condition. Book is flat, tight and clean. Additional Details ------------------------------ Product description: Volume 1. A-M & Volume 2. N-Z Entries are listed in a simple letter by letter alphabetical order, with spaces, hyphens, and the definite and indefinite articles being ignored... The Companion contains a system of cross-references that is designed to inform the reader of related entries; this should be particularly useful for anyone less familiar with the more specialized medical vocabulary encountered in some of the entries... The cross-referencing does not attempt to be comprehensive but aims to guide the reader towards entries that might enhance the understanding of the entry being consulted.
