Dictionary wanted

  J.L.(Zeph) Zephier (ishnajin at webtv.net)

  I am a Nakota Sioux, from the the Ihanktonwan Oyate, in South Dakota.
  I've been searching for a Nakota dictionary.  As of yet my search has
  been in vain.  Does anyone have an idea where I can find one?  Thank You!

                                                                   --"Zeph"
