Yes, the new Olive book is in English. I have been corresponding with
Dr. Tursch regarding this book. I am told that it will contain very much
of the material he (and others) published in the 28 papers, "Studies On
Olividae".
I believe it is a MUST purchase for Oliva collectors. Even if you don't
agree with his theories on speciation, you will have much food for
thought.
