The Louisiana Division of Archaeology is part of the state's Department of Culture, Recreation and Tourism. Their website offers a multitude of resources, including their homepage "What Do I Do if...?" section that helps those in Louisiana who might find artifacts on their property, an archaeological site, or an old burial site. Another helpful guide on their homepage is the "Are you looking for information about" section. Visitors should take a look at the "free books about Louisiana archaeology" to see the available books that can ordered for free, or just read directly from the site. Some of the titles include "Indian Mounds of Northeast Louisiana: A Driving Trail Guide", "El Nuevo Constante", and "Poverty Point". Visitors will enjoy the interactive "Los Adaes Site Explorer", at the bottom of the page, which highlights the Spanish mission built in the early 1700s to protect land that is now Texas, Florida, and Mexico.
