Conservation for archaeological wooden materials

I've got the following book. 

• Higami, N. 2012. Conservation and Its Consequences of Archaeological Wooden Materials (Shutsudo Moku-seihin no Hozon to Taiou, Handbook for Archaeological Surveys 4).  165 pp. Doseisya, Tokyo.

I'm just starting to read it, and it contains the details about many methods to conserve archaeological wooden materials from archaeological sites. Also, this book shows the method to draw tracing figures by Adobe Illustrator, and so it is very helpful for me.
