Query: A reprint of an outdated book

This book was first published in 1928. Since that time our understanding of ancient Mesoamerica has changed dramatically. This is a verbatim reprint of the original book, with a new introduction that sets Spinden and the book into historical context. If one is interested in the development of ideas about Mesoamerica in the early 20th century, this is a useful book. If one wants to find out about those civilizations, however, this is NOT the book to read. Many of Spinden's ideas were proven wrong in the 1930s; by 2000, the number of errors in the book is enormous. There has been much fieldwork, decipherment, and other research on these cultures in recent decades. Look for one of the many recent books about the Aztecs, Mayas, and other Mesoamerican civilizations. Dover should continue reprinting codices (the Codex Borgia and Codex Nuttall are great reprints!), and stay away from outdated textbooks.
