Encyclopedia of Green Woodworking by Ray Tabor.  Second edition, first published in 2000.

One of the most definitive titles currently available on green woodworking and traditional woodland craft.

Ray Tabor was a warden for Essex Wildlife Trust's Shadwell Wood Nature Reserve for over 25 years.  He pours his skills and experience into this book.

This is an encyclopedia of materials, tools and techniques in green woodworking. All supported by crystal clear line diagrams and explanations.

The section on the properties of wood is a particularly useful introduction. An indispensable resource.

All Ray Tabor other titles, sadly now mostly out of print, are essential reading.

ENCYCLOPEDIA of GREEN WOODWORKING is well written and clearly illustrated.
