The book is a handbook about how to create and maintain a volunteer program. While the specifics, such as job duties, focus on library volunteers, this handbook can truly work for any organization that can benefit from volunteers. And let me tell you, from my experience, almost any organization can benefit from volunteers! You can read more about my writing and researching process here.
I pulled from my background of creating the volunteer program for a nonprofit to lay the groundwork, so that information applies to any organization. Sample paperwork is even include, which can be copied directly from the book, or tweaked a bit for specific organizations.
I genuinely think this book can benefit many organizations. It's not a book that I would ask friends and family to buy to show their support, but please consider recommending it to your local library or any nonprofits you know that use or could use volunteers! That's the best way to help this book make a difference.
