Dear Colleagues,
Is there a way to buy the complete set of Handbook of the North American Indians, William C. Sturtevant, General Editor

https://bookstore.gpo.gov/catalog/minorities-cultures-languages/american-indians/handbook-north-american-indians

as one purchase?  It appears that the US GPO does not currently have all of the volumes in print.

Your help, ideas, suggestion for this would be greatly appreciated.
Thank you.
Yours truly,
Daniel Pagano
