Jo Kata and History

[taino1]

Hello,

Would anyone be able to recommend a good book or resource that goes through some basic Jo kata movements? Of course, you can never substitute a good teacher, but for solo practice this information may suit my purpose.

I'm a Gendai Jujutsu student and would like to begin undersanding some practicle uses for the jo, not to mention the rational behind certain Katas, and even some history behind them.

Thanks in advance...
