A white paper is an informational document that presents information, expert analysis, and an organization or authors insight into a topic or solution to a problem. It is meant to help readers understand an issue, solve a problem, or make a decision. White papers are more technical and in-depth than other types of content, such as blogs and case studies, and they use research, statistics, expert opinions, and original analysis to promote a product, service, or methodology. White papers are commonly designed for business-to-business marketing purposes between a manufacturer and a wholesaler, or between a wholesaler and a retailer. They are sales and marketing documents used to entice or persuade potential customers to learn more about a particular product, service, technology, or methodology. White papers are also used by other organizations, such as research institutes, universities, nonprofit groups, and government agencies, to present findings and guidance, and to propose policies and initiatives. The term "white paper" originated in Britain, where it refers to a type of government-issued document. Today, a white paper is the first document researchers should read to better understand a core concept or idea.
