Bass Guitar Fretboard Roadmap

I'm considering buying one or both and wondering which is better (or maybe another I've missed out). I already have The Bass Handbook (http://www.amazon.co.uk/Bass-Handbook-Complete-Mastering-Guitar/dp/0879308729/ref=sr_1_1?ie=UTF8&s=books&qid=1277740438&sr=1-1) but I was looking for something smaller.

Get yourself a couple of double bass books - Yorke Method for double bass vol.1 & OUP's Double Bass solo 1, work through some of that stuff and use all of the double bass fingering. Then see if you can find a copy of "The Literate Bassist" by Fred Paterno on ebay or Amazon.
