That's a book by Soltis. I too have the 1995 edition (I don't know anything about the 2013 edition).
One thing that stood out to me over the years about this book was the instruction about Caro-Slav structures. I'm not sure how useful it was even in a general sense. A lot depends on the pieces that are on the board and where they are, it seems to me. When first learning these openings I had a feeling (because of this book) that I should try to get in ...c5 or ...e5 soon or I'd surely be destroyed in most games. After a while I learned to relax more and instead usually just follow theory or advice I got from books on these openings that I might remember.
