Fleetwood Mac Anthology Songbook

[Bm7th]

I received the Fleetwood Mac Anthology songbook for Christmas and was quite disappointed that the book did not have any Lindsey Buckingham songs in it. It also did not have any tablature for guitar just the chords for the songs.

The one good thing about the book is that it has "Fireflies" and the chords are - G - Bm7-D-Am7- then on the part "long distance winner..... it's Em- D - Am7- G

My question is how accurate are the songbooks for piano, vocal and guitar?
