I use ;
"The real wood bible"
and
"World woods in color"
Book nr1 has much nicer pics, nicer to read since it has a spiral metal binding
in the back which makes it so easy to open the pages and it lasts...
Pics of the wood is done with %50 of the wood sealed with clear
and the other part "normal" wood.
Book 2 is as you can see mentioned by many - but not as crisp pics, however
have a OK table in the back showing the recommended use of the different species.
I use both since they complement them self - and have had me very rarely
put in front of the Mac for a Google exercise.
