Hello,
I just passed my ITIL Foundation exam. I'm very happy. I studied for about 30 hours. 2 books were key to my success, firstly I used ITIL Foundation Study Guide by Liz Gallacher and Helen Morris. I found this book much easier to read and comprehend than other books I had browsed and it proved essential to my passing this test. I could NOT have made it without reading this book.
I also browsed Edward Chung's blog at: 
My Complete ITIL v3 Foundation Certification Journey - Study Resources and Tips
It was full of useful info and his blog plugged a lot of holes I had in my knowledge, hats off to him for providing such an essential ressource.
I also bought a last minute book from Christopher Scordo: ITIL Exam Prep Questions and Answers. I bought this last minute when I ran out of example tests and questions. I'm very happy I did. This book is very thorough. It help me better grasp the ITIL language and the ITIL question types.
Thanks to all that posted in these forums, the information I found here was key to my passing this exam,
M
