Several websites provide information directly and pointers to other resources.
The best resource for books on volunteer management is http://www.energizeinc.com. My volunteer management "bibles" are "Help-I-Don't-Have-Time-To-Manage-Volunteers" and "From the Top Down," which are both available from this web site. There's also a great deal of volunteer management information at http://www.serviceleader.org. Finally, once you have plowed through the basics of volunteer management info, you might join CYBERVPM, which is a discussion group for volunteer managers. However, I encourage you to get to know the basics first before you start posting questions to this group. You can learn about CYBERVPM at http://groups.yahoo.com/group/cybervpm/.
The Cost of a Volunteer, published by the Grantmaker forum on Community and National Service, details the level of infrastructure neccessary for an organization to effectively involve volunteers. It's based on an assessment of 26 "high quality" volunteer programs. http://www.pacefunders.org/publications/pubs/Cost%20Volunteer%20FINAL.pdf
The United Nations Secretary General's Report "Support for Volunteering" (A/56/288) is now available on the UN Documentation Center Web site (http://www.un.org/documents). It is available in six different languages.
