The Carnegie Maya IV is the fourth in a series of volumes that make available the primary data and interpretive studies originally produced by archaeologists and anthropologists in the Maya region under the umbrella of the Carnegie Institute of Washington's Division of Historical Research. Collected together here are the Theoretical Approaches to Problems papers, a series that published preliminary conclusions to advance thought processes and stimulate debate. Although two of the three theories published in these reports have since been proven wrong, the theories themselves remain significant because of their impact on the direction of archaeology.

Only a few sets of these three contributions to the Theoretical Approaches to Problems series are known to have survived, making The Carnegie Maya IV an essential reference and research resource.

The corresponding ebook, for individual download, contains the complete set of The Carnegie Maya, The Carnegie Maya II, The Carnegie Maya III and The Carnegie Maya IV, thus making hundreds of documents from the Carnegie Institution's Maya program available in one source.
