The Mike Downes "Jazz Bass Line Book" is the one you want, I don't recall if it has tab, but its what you want. Mike Downes is the Bass Dept Head at Humber College in Toronto, and it was a required text when I was there. The included transcriptions and analysis alone are worth the book.
I'm pretty sure it can be found in PDF.
I havent seen this book, but it gets great ratings on Amazon. Review below:

5.0 out of 5 stars Best resource for walking bass lines as far as I've seen....so long as you know basic theory and how to read.

This is a fantastic book on walking bass lines. Most other books I've seen have been very similar in their approach, and while this book travels the same ground as many of the other books it does so in a much more complete way, and with a lot more meat thrown in. This also means that this book isn't for the complete beginner.
First, It doesn't start you off like most other books that spend a lot of pages teaching how to construct chords and put together scales. It's assumed that you already can do that stuff. Nor does the book start off with having you play the root through the whole progression. Rather, you start right in on chordal bass lines. Also, no tab here. So if you don't know how to read you're going to want to stay away from this one.
This book also tackles a lot of stuff I've seen most other books either not cover at all or just gloss over. For example, he covers stuff like over the bar line phrasing, ballad playing, 3/4 walking, and broken bass lines(think Scott LaFaro with Bill Evans). This is also the best treatment of playing in 2 that I've seen in a book. And he doesn't just spend a page on all these topics...they have whole sections.
Another awesome thing is the book contains several transcriptions from bass players throughout the years on blues(all in the same key so you can compare the approaches), and on rhythm changes. It's even set up where all the transcriptions are written lined up across several pages. It's hard to explain in words, but basically you can look on the page and see from bar to bar exactly what each bass player was doing. So, for example, I can see how Paul Chambers handled the 4 bar blues turn around as compared to Gary Peacock and Miroslav Vitous..and it's all right there on one page for easy comparison. Fear not though, there are also fully printed out transcriptions for all these parts so you can play them easier as well.
So if you really want to study walking bass aside from doing your own transcribing, and you already know some basics of music and how to read I would pick up this book without hesitation. Other walking books I've seen are child's play in comparison to this one. This is the real deal.
