Warcraft WealthThis guide is very well structured and it has zero fluff. It’s aimed only at making gold
The “noob” part shows the easiest ways to make gold at a low level. The “advanced” part presents some cutting-edge techniques for making gold fast (even Wayne’s personal method that made him 5,124g in 22 hours).
Plus, this guide includes some insider secrets about Auction House (2 videos) that many level players never heard about.

WoW Gold Secrets
Written by Luke Brown this book is the original Gold Guide that started it all. In publication for nearly 3 years. WoW Gold Secrets is a massive guide, about 220 pages long and has a ton of gold making info in it. It features many little secrets tips and tricks.
I find their special Gold Newsletter particulary useful when there’s hot gold tip that you got to know quickly before it is common knowledge.

Valkor Gold Making Guide
This book focuses entirely on gold making and Valkor is definitely the master. The book is filled with over 120 pages of detailed guide of gold farming. One of my favourite features is that it covers gold making for each professions, and it also cover a lot of lower level farming (handy when you’re new to WOW and don’t know how to earn your first mount)
This book is very easy to follow, easy to read and professionally done with great screenshots.

Warcraft RichesI was shocked to see a video of 27,000g in his bag, but this could have a been a fake video, you never know for sure.
Dereks Gold Guide has about 110 pages of your standard gold guide, but the main highlight is the auction house strategy that he claims to have earn all his masses. I feel that the guide needs to be a bit more detailed as some explainations are a bit short. and using his techniques can be a bit hard when there are other auction people doing the same thing.
