Hi Maria,
I looked around online and I couldn't find a more recent edition, so even though it's a few years old, I think the 16th Ed is the one.
At least I hope that's the case, since that's what I bought! Having received it in the mail over the weekend, it's a whale of a book. There will be lots to go through before October 23.
Aside, a friend of mine recommended Goswami All-in-One, which is apparently a less verbose than Lindeberg. I believe All-in-One is currently on the Third Ed (2015, with the blue cover), but the Fourth Ed is coming out in mid September. I'm going with the Third Ed, as I think Sept is a bit too close to the exam to be getting a new reference!
Good luck,
Dan
