Thanks to Rosanna Tarsiero I’ve just come accross “Volunteer magnet”, a book that’s as peculiar as practical for people who work with any type of volunteers. The title is very descriptive, and the authors’ presentation is a good introduction:
Turn Your Organisation Into a Volunteer Magnet is a knowledge-sharing
initiative within the international community of volunteer
programme managers (VPMs) for the purpose of peer-to-peer
professional development. The editors and writers have given their
time for free and it is the intention that nobody should profit from the
sale of this publication.
You can download it from here.
