Well, that's certainly going back some, Steve. I had a copy of this book sometime in the late 80's and it was out-of-date then. Anyway, the book "The Asahi Pentax Way" (Herbert Keppler - Peterson's PHOTOgraphic Magazine, etc) was written sometime in the mid-60's and revised several times through roughly the early 80's (your 1976 edition isn't the most recent).
It's primarily a general photography book, listing only in passing some of the earlier, mostly screw-mount, Pentax cameras (summary of features, etc). Of course, when talking about photography in this case, I'm referring to film photography from the 70's and early 80's. Virtually every product mentioned in the book (film, light meters, flash units, etc) was discontinued decades ago and very little about general film photography from that many years ago relates all that well to digital photography today.
Regardless, as Mike said, it's not too difficult to find inexpensive copies, so the book might be worth a casual look just to see what photography was then and how things have changed since. But, beyond that, the book really isn't going to offer much.
By the way, while medium format cameras may have been mentioned in passing, I don't remember any in-depth coverage. In fact, I don't remember in-depth coverage of any camera.
