The textbook by Editorial Santillana is a key educational resource used in secondary and higher secondary levels (such as Polimodal in Argentina) to analyze the complex relationship between human interaction and mass communication.

If you are a teacher and cannot afford class sets of the Santillana textbook, contact the publisher directly. Santillana has social programs and scholarships for underfunded schools. Writing to their customer service with your school’s information may grant you free or heavily discounted access to the official PDFs, including Chapter 13. This is far more effective—and legal—than searching the dark corners of the internet.
