Query: The Chilam Balam series

The Polpo Vuh is also written by the Maya of Ancient America. It predates the Chilam Balam series by at least 4,000 years. This is written as a correction to the previous reviewers notes on the Chilam Balam. It is important to purchase these books while they are available to us, the American Aboriginal from any part of the Americas while there is peace. None of the California Public librarys carry any of our ancient texts as they still marginalize our needs. You can always get Ancient Classical Greek works in public librarys across the country and anything from across the ocean but our own American original pieces are not made available to us still. So, if you can please purchase these books, and the Popol Vuh and donate them to your public librarys while we still have a chance to recover from the on going conquest.
