What should I be reading?

When I get interested in something I like to read up on it and learn as much as i can. So long post short, what books, blogs, and forums should I be reading?
Right now I keep a pretty close eye on:
Cigarasylum (obviously)
Stogieguys (pretty regularly)
cigarinspector (less regularly)
cigarcyclopedia (just added this to my list)

I'm definitely looking for a couple books, but blogs, and anything else are welcome. Thanks in advance for any recommendations.
