This bibliography is a current source of information for researchers, practitioners, and planners interested in the older volunteer. The authors conducted an extensive search of material on the older volunteer, with emphasis on those works published between 1980 and 1991. After identifying approximately 700 sources, the authors selected nearly 400 for inclusion in this reference. The entries are grouped in seven topical chapters, and each entry includes a succinct annotation. Included are entries for books and articles on particular programs, characteristics of older volunteers, sources of statistical information, empirical research, and special population groups. Author and subject indexes conclude the work.

This book constitutes the proceedings of the 13th German Conference on Multiagent System Technologies, MATES 2015, held in Cottbus, Germany, in September 2015. The 11 full papers papers presented together with 2 short papers, 1 invited paper and 4 extended abstracts of doctoral papers in this volume were carefully reviewed and selected from 27 submissions. The papers are organized in topical sections on MAS engineering, modeling, and simulation; smart things working together; and innovative and emerging applications of MAS.

This book constitutes the proceedings of the 12th European Conference on Multi-Agent Systems, EUMAS 2014, held in Prague, Czech Republic, in December 2014. The 21 full papers and 8 short papers presented in this volume were carefully reviewed and selected from 79 submissions. They are organized in topical sections named: agent-based models, trust and reputation; coordination, coalitions and teamwork; logic and formal approaches; theories in practice and real-world problems; decision making, conflicts and agreements.

This book constitutes the proceedings of the 15th International Workshop on Computational Logic in Multi-Agent Systems, CLIMA XV, held in Prague, Czech Republic, in August 2014. The 12 regular papers were carefully reviewed and selected from 20 submissions. The purpose of the CLIMA workshops is to provide a forum for discussing techniques, based on computational logic, for representing, programming and reasoning about agents and multi-agent systems in a formal way. This edition will feature two special sessions: logics for agreement technologies and logics for games, strategic reasoning, and social choice.
