I highly - HIGHLY recommend this book to anyone who wants to teach aboard. For the record, I'm American, and while some of the information does talk about interviews in the UK or whatever, I've found it to be a HUGELY helpful resource for job-hunting. The GF and I are using the book to look for jobs in Asia, and it's been invaluable.
This book will answer your basic questions about almost any country in the world: what's it like to live there, what are the teaching conditions like, how much will I be paid, what's the cost of living, etc. It also lists reputable schools in each country and gives their contact info - a REALLY REALLY valuable resource!
The information in the book is clear, straightforward and well organized - pretty much the opposite of searching online. I really can't overstate how immensely great this book is - especially compared to the other options: Google searching, forums full of trolls, etc.
Getting a job teaching English abroad could be as easy as:
1. be qualified
2. find a country you like in the book
3. send your resume, etc to schools listed in the book
4. hopefully get some interest, and some offers
