From the book’s description:

Don’t Throw the Book at Them addresses one of the most vital issues in contemporary missions. It is a manual for cross-cultural missionaries and national church leaders ministering in societies based on oral rather than written communication. Harry Box, former missionary and researcher in Papua New Guinea and among the Aborigines of Central Australia, explains the distinct characteristics of oral societies, how they differ from literacy-oriented societies, Jesus’ ministry to oral communicators, and why effective presentation of the Christian message demands that Western Christians change their approach to orality. The book goes beyond case studies and analysis, allowing the reader to develop a detailed plan for communication.
