The Librotraficante Caravan is bringing contraband books--or "wet-books"--to Arizona. The project is also intended to raise awareness of the "prohibition" of the Mexican-American Studies Program and the removal of books from classrooms.

"When we heard that Tucson Unified School District administrators not only prohibited Mexican-American Studies, but then walked into classrooms, and in front of young Latino students, during class time, removed and boxed up books by our most beloved authors - that was too much. This offended us down to our soul. We had to respond," said Tony Diaz, founder of Nuestra Palabra: Latino Writers Having Their Say, which has led the charge.
