Joni fans/guitarists - do you know about the book 'Complete So Far..'?

I did not know of it but it seems it was published in 2014. It has the music and lyrics for all of her songs but more importantly has the correct tuning for each.
My beautiful and exceptional wife bought it for me this Christmas and it is a key into another world. The first song I went to was Coyote - which is tuned CGDFCE - and playing it was like looking at a photo album and the pictures starting to move and talk. These songs that I’d never been able to play suddenly sounding and feeling RIGHT was almost overwhelming.
If you have any interest in her songs or guitar geekery I cannot recommend this book highly enough.
It’s a big book and suitably expensive at £55 or $75 but for me, (and hopefully my wife) worth every penny.
