Here's a run down of the books (thanks to Amy):

Little Earthquakes: Includes a lot of melody in the left hand, missing the solo to Leather and the intro the Mother (among other things). Doesn't sound terrible when played correctly, but can be disappointing. Includes Upside Down and Thoughts.

Under the Pink: Very accurate, though slightly toned down. Missing intro's to Icicle, Yes Anastasia, and everything interesting in Cornflake Girl. Includes Over It and All the Girls Hate Her. Challenging.

The BeeSides: Though it does meander along with the vocals some of the time, Tori's beesides have a lot of extremely complex movements in them that this book displays with sometimes surprising accuracy. Randomly, this includes Etienne, Floating City, and Baltimore. Mixed difficulty.

Boys For Pele: Very complete, with some puzzling spots. Horses is excellent, and it includes the intro to Muhammed My Friend, but Caught A Lite Sneeze isn't quite right. Overall a fair challenge to play.

Choirgirl: Not very accurate. Nearly everything follows the melody with the left hand, right hand often substitutes the bass parts, a few songs are toned down. Very playable, but mostly because of the transcriptions.

Venus and Back: Well done, with obvious exceptions on synthesizer songs (Juarez, Glory of the 80's). Bliss and shockingly Datura, are nearly perfect. The live songs are all reprinted VERBATIM from their original books; the new transcriptions of Cooling and Purple People are strong. New material is of medium challenge.

Scarlet's Walk: This is one of the first books since Pele to be accurate, and not only that, but its release date was pushed back so Tori could personally work on the transcriptions.
