Recommendations on books for beginners

[khozmo]

I have purchased the Orth book "Complete guide to orchids". I was wondering what other books people have bought over the years that have given them good insight into the world of orchids. Looking for those books that you always find yourself running for ,for emergencies, sanity checks and good old common sense.

(please no books on how to curb orchid addiction, I like my world they know me here)
