This monograph explores the concept and practice of college and university outreach through faculty professional service, in which faculty help both meet societal needs and fulfill their institution's mission through work based on their scholarly expertise. It points out that professional service by faculty can become a source of innovation and discovery in scholarly theory and methodology; enhance the quality of instruction, especially in professional education; and be intellectually invigorating for faculty themselves. Such work also provides a direct intellectual resource for the institution's external constituencies. Professional service can take a variety of forms, including technology transfer, technical assistance, policy analysis, program evaluation, organizational development, community development, program development, professional development, expert testimony, and public information. Five case studies exemplify outreach projects demonstrating the potential for scholarship in such work. They include projects to chronicle the development of a state professional association, develop geological field study guides for elementary and secondary education, develop a curriculum for ethics instruction in police academies, improve a chemical manufacturing process for a small company, and assess an English language program for immigrants. Ideas for departmental discussion are provided. (Contains 35 references and substantial appended readings). (MSE)
