This book is a unique approach in relating mutually international and comparative research from scholars on program planning for adults. Program planning is about needs, finding topics, making offers and bundling different contents. It makes organizations of adult education visible and contributes to their existence and is therefore a core activity of the professionals in adult education. The volume originates from an international conference hosted by Leibniz—University Hannover, which was organized by a plural expert group with key actors at Humboldt—University Berlin and the German Institute for Adult Education. The authors demonstrate the unique research method program analysis and present archives which offer an established infrastructure for heterogeneous research questions.
