PPC Books/eBooks Recommendations?

[addz123]

Can anyone recommend any good PPC books or ebooks that are fairly up to date and include case studies with information like CTR and ROI etc?

Thanks.

Adwords for Dummies is very good but a little bit dated (doesn't feature image ads at all iirc)

Doesn't have in-depth case studies but does compare different ads to show how CTR improved.

The white paper I wrote a couple of years back about exact match domains and PPC may be worth a read, since unlike SEO there's no dependency on a Google "exact match bonus" or similar since you're paying to show up in the ads anyway...
