What sets workbooks apart from books per se?

• Workbooks are designed to engage readers to interact with the material to a far greater extent than books—readers don't simply read but "work through" workbooks.
• Workbooks are less word-intensive and generally shorter than trade books.
• Workbooks are designed for use in small groups (i.e., stimulate discussion and group interaction).
• Workbooks should make extensive use examples drawn from real-life (or at least realistic scenarios) that illustrate the concepts and principles presented. The use of story as testimony is an important element of effective supportive caregroups.
