Fabio Ausenda has masterfully prepared three volunteer guides to help those who wish to help others. Each book lists hundreds of organizations from all over the world. A summary of each organization is detailed with a description of each program, contact information, cost, duration, how to apply, and much more.

Whether your interests lie in environmental conservation, humanitarian aid, or archaeology, these books will provide you with an abundance of options. Volunteering opportunities of all kinds are included, including short-term volunteering (one to three weeks) and long term (one month, a year, or more). One will not find guides more definitive or informative.
