Books on Tree Care

[Big O]

99% of the discussion and available reading out there seems to be on climbing and rigging. I'm looking for suggestions on your favorite books specifically concerning tree care. Any must reads, don't even bother withs or those aimed at a specific area of tree care ie, pruning, disease, cableing? I could list some of the books available to select from but would prefer to hear your suggestions many I may not have knowledge of.
Thanks
