This pamphlet on working with volunteers is the tenth of 16 in a series to provide leaders in adult activities with sound introductory material to give practical help in using a method of adult education or working in a particular area. Its objective is to help volunteers and the professionals who work with them improve their effectiveness. Seven articles and how-tos are included. "Who Volunteers and Why?" and "How Some Find Time to Volunteer" look at the motives of the volunteer and at the homes and problems they may have left behind. "The Role of the Recruiting Agency" tells what the agency wants to get out of the relationship and suggests some ways it can help itself to get it. The next three articles deal with the three most significant points of contact between the professional and the volunteer--"Placement,""Training," and "Supervision.""Volunteers in the Church" presents the volunteer within a particular institutional setting and takes up the problem presented when the volunteer is more highly skilled at the job he has taken on than the professional with whom he serves.
