Dear Vikrant Wood and coal tar formed the backbone of organic chemistry in the late 19th and early 20th century. Older libraries will sometimes have a LOT of information on production and use of wood tar.
I read the book written about 1920 that I found in the Colorado School of Mines library with great fascination.
