I know this is is an old thread being resurrected, but that's what the search button is for... to not start a new thread on the same subject.
I just got The Bass Tab White Pages yesterday. I can't say I went through it extensively, but for what I've seen I think I can't have gone wrong (especially with my company discount

).
I think at the very least it will show me what I am doing right and what I am doing wrong in playing around with making up my own bass lines. I like the idea of the standard notation; since this is something I've neglected since college music courses 30 years ago.
I'm looking forward to using it.
