Books about Direct Mail (preferably recent)

[Kyle McCorkel]

Does anybody have any book (or podcast/blog) recommendations that mainly focus on all aspects of direct mail? I'd be looking for something hopefully recent (within the last 2-3 years) that would include recommendations on tools and resources (such as list building sites/services) as well as different strategies: driving for dollars, pre-foreclosures, probate, etc.

Thanks in advance for any recommendations!
