A Guide for Archaeologists and Conservators

This technical and well-illustrated guide for archaeologists and conservators aims to `provide a methodology for the identification of the woody taxa used to manufacture artefacts recovered from archaeological excavations’, to provide the anatomical descriptions of the taxa and to present a list of characters of the taxa. The guide is heavily illustrated with photographs, maps, and tables to allow easy identification.
