Gentlemen,

I found this publication (?) cited in a bibliography:

"Indian Cavalry in Confederate Service: Being a brief Account of Confederate Organization and Operations of Indian Troops in Indian Territory 1861-1865", compiled/ prepared/ published (?) by the Thomas Gilcrease Institute in Tulsa, OK.
I am curious as to what kind of document this is and what information it may contain. Perhaps some of you who are located not too far away from the Gilcrease Institute would care to investigate? E-mail inquiries to the Institute has yielded no response.
