I am looking at my copy of this book right now.I purchased it in 1980. It has hundreds of chord diagrams for chords played with the open harmonics.

I did a search, Google, for the book and found it for sale for $160.00!

I couldn't locate "free-bass press" in Eugene, Oregon.
I finally found it here for $15.00:
