The one absolute must read if you read no other is: "The Perfect Shot" by Dr. Kevin "Doctari" Robertson.
He is a member of this forum under the screen name of Doctari505.
However, some other person in this forum told me recently that the larger/hard bound version of that book is out of print lately.
However, there is an abbreviated, soft cover/pocket size version that I notice is still for sale in a local sporting goods store, here in Alaska.
