Small book being about 4 1/8" x 5 3/4" in Good condition. A few defects but not so bad. There is scuffing at the top of the spine, the covers are a bit soiled and the first few pages have some bug bites. None of that too awful and the major part of the book is okay. Small glossary insert provides revisions on some terms. This tome is apparently in demand and nicer condition copies are going twenty-five to thirty-five each. So if you would like to have a copy for reference but not spend too much on it, here it is.
