The United States is home to about 1.3 million organizations that fall under the IRS's 501(c)(3) classification of "[tax]-exempt organizations," known informally as nonprofits. A nonprofit is defined as a formally incorporated nongovernmental organization that operates in the public interest, rather than in order to make a profit. Its income, in other words, is used to enact its mission. Nonprofits may include schools and universities, social service and religious organizations, cultural and scientific groups, hospitals, and public libraries. However, "tax-exempt" does not mean that nonprofits pay no taxes whatsoever, nor does it mean that all contributions to them qualify for tax deductions. There has been a surge of interest in the last several years on how to start nonprofit groups, including public libraries that would like to establish a separate 501(c)(3) fundraising arm for their otherwise publicly funded institutions. Likewise, an increasing number of nonprofits want to know how to obtain funding from grant-making foundations and government agencies. There is a need for libraries to offer a well-rounded collection of books, periodicals, and web sites that comprehensively covers this subject, including nonprofit formation and management and realistic approaches to obtaining grant support. Such a collection will offer both proposal writing books and materials on other forms of fundraising, including guides aimed at individuals, small grass-roots organizations, and the large well-established ones. There should also be resources that focus on particular fundraising mechanisms, such as special events, mailings, or annual campaigns. Another issue for nonprofits is how to create a hard-working board that can oversee the organization without micromanagement and that can work with the staff in fundraising efforts. This article presents a bibliography of titles in this field that are considered essential for all public library collections. Larger libraries and those serving nonprofit organizations should consider the entire list. (Contains 18 resources and 4 online resources.)
