Would you recommend this book?

[gleeok]

I've heard that opinions on piano techniques are wide, and sometimes even clash with each other, so... I've been skeptic about ordering any book on piano techniques or anything that touches that subject too strongly, because I think there is no such thing like " the best technique" out there. But I saw this might contain some good information either way, would you recommend it? How useful will it be for a beginner and practically inexperienced player in therms of formal learning?

"It is a clear, detailed, and practical guide to authenticity in performance which all keyboard players will find indispensable"

Thats why I'm asking, keyword; "guide".

Thank you! And thanks for those who recommended Thomas Mark's "What every pianist needs to know about the body", I took great advices from it and I'm still enjoying it. And it seems the pain I used to feel after very long and obsessive sessions of playing is like almost, completely gone, no matter how long I play in a single day!

Haven't read the book, but from the description it appears to discuss period performance practices from the 14th to 19th centuries.  If you have an interest in playing music of this period, it would be good to read.

For the beginner, it probably isn't the best "starter" book to go by.  One would more likely better appreciate the knowledge of period performance if one already has some knowledge of modern piano technique.  

On the broader topic of piano technique, I would recommend at the very least to be reading on not just one, but several different perspectives of the subject.  Don't take any single tome as the bible, but decide for yourself what works.

Agree with quantum. I would also add that no book is a substitute to listening to as many performances as you can. YouTube or equivalent is you friend.
