The Bill Nibbelink Papers documents Nibbelink’s involvement in the development and promotion of alcohol fuels in South Dakota, reflecting his collaboration with Congressman Tom Daschle and regional organizations during the late 1970s and early 1980s. The collection includes a range of government and industry publications on ethanol, such as materials produced by the U.S. Department of Energy, the Department of Agriculture, the Solar Energy Research Institute, and local advocacy groups like the South Dakota Alcohol Fuels Association. These materials illustrate a critical moment in the push for renewable energy solutions in the Midwest and highlight Nibbelink’s role in distributing and producing outreach materials to support the cause.

In addition to energy policy materials, the collection contains assorted campaign memorabilia and planning documents, including a 1978 recount handbook from the contested congressional election in Moody County. These records offer insight into grassroots campaign operations, local political strategy, and the resourcefulness of early campaign efforts with limited funding. The presence of "Get Out The Vote" materials and memorabilia spanning from 1978 to 2004 captures the longevity of Nibbelink’s political engagement.

Also included are constituent correspondence files known as robo letters, which detail how Daschle’s congressional office handled communication with constituents during his early terms. These are complemented by logistical materials such as South Dakota trip schedules, contact lists, and a congressional telephone directory, providing a fuller picture of day-to-day congressional operations.

Photographs, press clippings, and a 2015 interview with Nibbelink round out the collection, adding visual and personal context to the professional and political records. Altogether, the collection serves as a valuable resource for studying early renewable energy advocacy, political campaigning in rural America, and the evolution of constituent service in congressional offices.
