I need to learn the basic and advanced ways to use MSN adcenter. Where can I find good learning material?

Any good books or blogs out there ?

Thanks,

did you find anything? i'm looking for this too!

MS provide some good starter videos on their site. I don't have enough posts to post a URL, but try Googling:
support center adcenter training

#1 result for me has some introductory vids.
