"...the handbook edited by Helmut Anheier and Stefan Toepler is indeed a very valuable companion to students and scholars of nonprofit research and management, because it helps to understand the diversity and complexity of the sector, it sheds light on the nexus between the context of the organization and the challenges or potentials, managers of nonprofit organizations are confronted with, in their daily work. Finally, the handbook constitutes an impressive resource for those who are engaged in nonprofit research because almost all the articles of the volume point to urgent issues that might be either related to the changed economic and political environment of nonprofits or to changes of the very nature of nonprofits itself." -Annette Zimmer, Institute for Political Science, Munster University, Munster, Germany
